3c80fe4 Thomas Gleixner 09 December 2009, 14:19:31 UTC audit: Call tty_audit_push_task() outside preempt disabled While auditing all tasklist_lock read_lock sites I stumbled over the following call chain: audit_prepare_user_tty() read_lock(&tasklist_lock); tty_audit_push_task(); mutex_lock(&buf->mutex); --> buf->mutex is locked with preemption disabled. Solve this by acquiring a reference to the task struct under rcu_read_lock and call tty_audit_push_task outside of the preempt disabled region. Move all code which needs to be protected by sighand lock into tty_audit_push_task() and use lock/unlock_sighand as we do not hold tasklist_lock.

d29be15 Miloslav Trmac 16 September 2010, 22:14:11 UTC Audit: add support to match lsm labels on user audit messages Add support for matching by security label (e.g. SELinux context) of the sender of an user-space audit record. The audit filter code already allows user space to configure such filters, but they were ignored during evaluation. This patch implements evaluation of these filters. For example, after application of this patch, PAM authentication logs caused by cron can be disabled using auditctl -a user,never -F subj_type=crond_t Signed-off-by: Miloslav Trmac <mitr@redhat.com> Acked-by: Eric Paris <eparis@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> 30 October 2010, 05:41:57 UTC

404ba5d Jason Baron 28 October 2010, 15:20:27 UTC x86, alternative: Call stop_machine_text_poke() on all cpus Currently, text_poke_smp() passes a NULL as the third argument to __stop_machine(), which will only run stop_machine_text_poke() on 1 cpu. Change NULL -> cpu_online_mask, as stop_machine_text_poke() is intended to be run on all cpus. I actually didn't notice any problems with stop_machine_text_poke() only being called on 1 cpu, but found this via code inspection.

bdf5005 Abdoulaye Walsimou Gaye 16 October 2010, 11:55:52 UTC ARM: S3C2440: fix boot failure introduced by recent changes in gpiolib Recent changes in s3c gpio break mini2440 board and may be others. The problem is that mach-mini2440.c: mini2440_init() (where we call s3c_gpio_setpull()) is called before s3c2440.c: s3c2440_init() (where we initialize s3c24xx_gpiocfg_default.set_pull function pointer). This causes dereferencing of NULL pointer at boot time and a kernel panic.

06125ff Daniel Walker 27 October 2010, 20:04:58 UTC msm: fix compile failure when no debug uart is selected If the board has a debug uart the user is given a choice of which uart to use. The user can also select NONE, which means not to use one. In most of our header files when NONE is selected nothing is defined for MSM_DEBUG_UART_PHYS or MSM_DEBUG_UART_BASE. This causes a compile failure in debug-macro.S which expect something to be defined there. Example of the failure, arch/arm/kernel/built-in.o: In function `hexbuf': linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_PHYS' linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_BASE' This fixes the compile failure by adding an ifdef to debug-macro.S that removes all the debug uart code in the case of NONE.

bcd72c3 Daniel Walker 27 October 2010, 22:25:59 UTC msm: fix debug-macro.S build failure Originally there was an ifdef case to handle when no debug uart was selected. In commit 0ea1293009826da45e1019f45dfde1e557bb30df that case was removed which causes the following build failure, linux-2.6/arch/arm/kernel/debug.S: Assembler messages: linux-2.6/arch/arm/kernel/debug.S:174: Error: bad instruction `addruart r1,r2' linux-2.6/arch/arm/kernel/debug.S:176: Error: bad instruction `waituart r2,r3' linux-2.6/arch/arm/kernel/debug.S:177: Error: bad instruction `senduart r1,r3' linux-2.6/arch/arm/kernel/debug.S:178: Error: bad instruction `busyuart r2,r3' linux-2.6/arch/arm/kernel/debug.S:190: Error: bad instruction `addruart r1,r2' This is a partial revert to add back the case which was removed with two caveats. First the API for the addruart macro was updated, and the new addruart case now return 0xfff00000 so that a know IO mapping is created instead of a random one.

520efd1 Jesper Juhl 29 October 2010, 14:10:26 UTC mac80211: fix failure to check kmalloc return value in key_key_read I noticed two small issues in mac80211/debugfs_key.c::key_key_read while reading through the code. Patch below. The key_key_read() function returns ssize_t and the value that's actually returned is the return value of simple_read_from_buffer() which also returns ssize_t, so let's hold the return value in a ssize_t local variable rather than a int one. Also, memory is allocated dynamically with kmalloc() which can fail, but the return value of kmalloc() is not checked, so we may end up operating on a null pointer further on. So check for a NULL return and bail out with -ENOMEM in that case. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: John W. Linville <linville@tuxdriver.com> 29 October 2010, 18:33:26 UTC

412910c Wu Zhangjin 27 October 2010, 10:59:08 UTC ftrace/MIPS: Add module support for C version of recordmcount Since MIPS modules' address space differs from the core kernel space, to access the _mcount in the core kernel, the kernel functions in modules must use long call (-mlong-calls): load the _mcount address into one register and jump to the address stored by the register: c: 3c030000 lui v1,0x0 <--------> b label c: R_MIPS_HI16 _mcount c: R_MIPS_NONE *ABS* c: R_MIPS_NONE *ABS* 10: 64630000 daddiu v1,v1,0 10: R_MIPS_LO16 _mcount 10: R_MIPS_NONE *ABS* 10: R_MIPS_NONE *ABS* 14: 03e0082d move at,ra 18: 0060f809 jalr v1 label: In the old Perl version of recordmcount, we only need to record the position of the 1st R_MIPS_HI16 type of _mcount, and later, in ftrace_make_nop(), replace the instruction in this position by a "b label" and in ftrace_make_call(), replace it back. But, the default C version of recordmcount records all of the _mcount symbols, so, we must filter the 2nd _mcount like the Perl version of recordmcount does. The C version of recordmcount copes with the symbols before they are linked, So It doesn't know the type of the symbols and therefore can not filter the symbols as the Perl version of recordmcount does. But as we can see above, the 2nd _mcount symbols of the long call alawys follows the 1st _mcount symbol of the same long call, which means the offset from the 1st to the 2nd is fixed, it is 0x10-0xc = 4 here, 4 is the length of the 1st load instruciton, for MIPS has fixed length of instructions, this offset is always 4. And as we know, the _mcount is inserted into the entry of every kernel function, the offset between the other _mcount's is expected to be always bigger than 4. So, to filter the 2ns _mcount symbol of the long call, we can simply check the offset between two _mcount symbols, If it is 4, then, filter the 2nd _mcount symbol. To avoid touching too much code, an 'empty' function fn_is_fake_mcount() is added for all of the archs, and the specific archs can override it via chaning the function pointer: is_fake_mcount in do_file() with the e_machine. e.g. This patch adds MIPS_is_fake_mcount() to override the default fn_is_fake_mcount() pointed by is_fake_mcount. This fn_is_fake_mcount() checks if the _mcount symbol is fake, e.g. the 2nd _mcount symbol of the long call is fake, for there are 2 _mcount symbols mapped to one real mcount call, so, one of them is fake and must be filtered. This fn_is_fake_mcount() is called in sift_rel_mcount() after finding the _mcount symbols and before adding the _mcount symbol into mrelp, so, it can prevent the fake mcount symbol going into the last __mcount_loc table.

949e51b David Daney 14 October 2010, 18:32:33 UTC MIPS: Make TASK_SIZE reflect proper size for both 32 and 64 bit processes. The TASK_SIZE macro should reflect the size of a user process virtual address space. Previously for 64-bit kernels, this was not the case. The immediate cause of pain was in hugetlbfs/inode.c:hugetlb_get_unmapped_area() where 32-bit processes trying to mmap a huge page would be served a page with an address outside of the 32-bit address range. But there are other uses of TASK_SIZE in the kernel as well that would like an accurate value. The new definition is nice because it now makes TASK_SIZE and TASK_SIZE_OF() yield the same value for any given process. For 32-bit kernels there should be no change, although I did factor out some code in asm/processor.h that became identical for the 32-bit and 64-bit cases. __UA_LIMIT is now set to ~((1 << SEGBITS) - 1) for 64-bit kernels. This should eliminate the possibility of getting a AddressErrorException in the kernel for addresses that pass the access_ok() test. With the patch applied, I can still run o32, n32 and n64 processes, and have an o32 shell fork/exec both n32 and n64 processes.

602977b Kevin Cernekee 16 October 2010, 21:22:30 UTC MIPS: Decouple BMIPS CPU support from bcm47xx/bcm63xx SoC code BMIPS processor cores are used in 50+ different chipsets spread across 5+ product lines. In many cases the chipsets do not share the same peripheral register layouts, the same register blocks, the same interrupt controllers, the same memory maps, or much of anything else. But, across radically different SoCs that share nothing more than the same BMIPS CPU, a few things are still mostly constant: SMP operations Access to performance counters DMA cache coherency quirks Cache and memory bus configuration So, it makes sense to treat each BMIPS processor type as a generic "building block," rather than tying it to a specific SoC. This makes it easier to support a large number of BMIPS-based chipsets without unnecessary duplication of code, and provides the infrastructure needed to support BMIPS-proprietary features.

3a9ab99 Deng-Cheng Zhu 12 October 2010, 11:37:24 UTC MIPS: Add support for hardware performance events (mipsxx) This patch adds the mipsxx Perf-events support based on the skeleton. Generic hardware events and cache events are now fully implemented for the 24K/34K/74K/1004K cores. To support other cores in mipsxx (such as R10000/SB1), the generic hardware event tables and cache event tables need to be filled out. To support other CPUs which have different PMU than mipsxx, such as RM9000 and LOONGSON2, the additional files perf_event_$cpu.c need to be created. Raw event is an important part of Perf-events. It helps the user collect performance data for events that are not listed as the generic hardware events and cache events but ARE supported by the CPU's PMU. This patch also adds this feature for mipsxx 24K/34K/74K/1004K. For how to use it, please refer to processor core software user's manual and the comments for mipsxx_pmu_map_raw_event() for more details. Please note that this is a "precise" implementation, which means the kernel will check whether the requested raw events are supported by this CPU and which hardware counters can be assigned for them. To test the functionality of Perf-event, you may want to compile the tool "perf" for your MIPS platform. You can refer to the following URL: http://www.linux-mips.org/archives/linux-mips/2010-10/msg00126.html You also need to customize the CFLAGS and LDFLAGS in tools/perf/Makefile for your libs, includes, etc. In case you encounter the boot failure in SMVP kernel on multi-threading CPUs, you may take a look at: http://www.linux-mips.org/git?p=linux-mti.git;a=commitdiff;h=5460815027d802697b879644c74f0e8365254020 Signed-off-by: Deng-Cheng Zhu <dengcheng.zhu@gmail.com> To: linux-mips@linux-mips.org Cc: a.p.zijlstra@chello.nl Cc: paulus@samba.org Cc: mingo@elte.hu Cc: acme@redhat.com Cc: jamie.iles@picochip.com Cc: ddaney@caviumnetworks.com Cc: matt@console-pimps.org Patchwork: https://patchwork.linux-mips.org/patch/1689/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> create mode 100644 arch/mips/kernel/perf_event_mipsxx.c 29 October 2010, 18:08:49 UTC

14f7001 Deng-Cheng Zhu 12 October 2010, 11:37:22 UTC MIPS: add support for hardware performance events (skeleton) This patch provides the skeleton of the HW perf event support. To enable this feature, we can not choose the SMTC kernel; Oprofile should be disabled; kernel performance events be selected. Then we can enable it in Kernel type menu. Oprofile for MIPS platforms initializes irq at arch init time. Currently we do not change this logic to allow PMU reservation. If a platform has EIC, we can use the irq base and perf counter irq offset defines for the interrupt controller in specific init_hw_perf_events(). Based on this skeleton patch, the 3 different kinds of MIPS PMU, namely, mipsxx/loongson2/rm9000, can be supported by adding corresponding lower level C files at the bottom. The suggested names of these files are perf_event_mipsxx.c/perf_event_loongson2.c/perf_event_rm9000.c. So, for example, we can do this by adding "#include perf_event_mipsxx.c" at the bottom of perf_event.c. In addition, PMUs with 64bit counters are also considered in this patch.

This patch adds the necessary 'glue' logic to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II. The OCTEON normally runs big-endian, and the ehci/ohci internal registers have host endianness, so we need to select USB_EHCI_BIG_ENDIAN_MMIO. The ehci and ohci blocks share a common clocking and PHY infrastructure. Initialization of the host controller and PHY clocks is common between the two and is factored out into the octeon2-common.c file. Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in arch/mips/Kconfig in a following patch.

7837314 Ralf Baechle 29 October 2010, 18:08:24 UTC MIPS: Get rid of branches to .subsections. It was a nice optimization - on paper at least. In practice it results in branches that may exceed the maximum legal range for a branch. We can fight that problem with -ffunction-sections but -ffunction-sections again is incompatible with -pg used by the function tracer. By rewriting the loop around all simple LL/SC blocks to C we reduce the amount of inline assembler and at the same time allow GCC to often fill the branch delay slots with something sensible or whatever else clever optimization it may have up in its sleeve. With this optimization gone we also no longer need -ffunction-sections, so drop it. This optimization was originally introduced in 2.6.21, commit 5999eca25c1fd4b9b9aca7833b04d10fe4bc877d (linux-mips.org) rsp. f65e4fa8e0c6022ad58dc88d1b11b12589ed7f9f (kernel.org). Original fix for the issues which caused me to pull this optimization by Paul Gortmaker <paul.gortmaker@windriver.com>. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 29 October 2010, 18:08:24 UTC

435f49a Linus Torvalds 29 October 2010, 17:36:49 UTC readv/writev: do the same MAX_RW_COUNT truncation that read/write does We used to protect against overflow, but rather than return an error, do what read/write does, namely to limit the total size to MAX_RW_COUNT. This is not only more consistent, but it also means that any broken low-level read/write routine that still keeps counts in 'int' can't break.

f16feb5 Roberto Sassu 06 October 2010, 16:31:32 UTC ecryptfs: added ecryptfs_mount_auth_tok_only mount parameter This patch adds a new mount parameter 'ecryptfs_mount_auth_tok_only' to force ecryptfs to use only authentication tokens which signature has been specified at mount time with parameters 'ecryptfs_sig' and 'ecryptfs_fnek_sig'. In this way, after disabling the passthrough and the encrypted view modes, it's possible to make available to users only files encrypted with the specified authentication token.

In particular keys are directly released in the same function if the obtained authentication token is not valid. Further, a new function parameter 'auth_tok_key' has been added to ecryptfs_find_auth_tok_for_sig() in order to provide callers the key pointer to be passed to key_put().
