dd173ab | Dan Carpenter | 06 September 2010, 12:32:30 UTC | Staging: vt6655: fix buffer overflow "param->u.wpa_associate.wpa_ie_len" comes from the user. We should check it so that the copy_from_user() doesn't overflow the buffer. Also further down in the function, we assume that if "param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is initialized. To make that work, I changed the test here to say that if "wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return -EINVAL. Oddly, we only use the first element of the abyWPAIE[] array. So I suspect there may be some other issues in this function.

350aede | Sven Eckelmann | 04 September 2010, 23:58:18 UTC | Revert: "Staging: batman-adv: Adding netfilter-bridge hooks" This reverts commit 96d592ed599434d2d5f339a1d282871bc6377d2c. The netfilter hook seems to be misused and may leak skbs in situations when NF_HOOK returns NF_STOLEN. It may not filter everything as expected. Also the ethernet bridge tables are not yet capable to understand batman-adv packet correctly. It was only added for testing purposes and can be removed again.

This patch fixes the two issues above: -power down phy only if no usb cable is connected with PC and b-device -do phy initialization(via __twl4030_phy_resume) if usb cable is connected with PC(vbus event) or another b-device(ID event) in twl4030_usb_probe. This patch also doesn't put VUSB3V1 LDO into active mode in twl4030_usb_ldo_init until VBUS/ID change detected, so we can save more power consumption than before. This patch is verified OK on Beagle board either connected with usb cable or not when poweron. [1]. warnings of 'unbalanced disables' of regulators.

31c4a3d | Hugh Dickins | 20 September 2010, 02:40:22 UTC | mm: further fix swapin race condition Commit 4969c1192d15 ("mm: fix swapin race condition") is now agreed to be incomplete. There's a race, not very much less likely than the original race envisaged, in which it is further necessary to check that the swapcache page's swap has not changed. Here's the reasoning: cast in terms of reuse_swap_page(), but probably could be reformulated to rely on try_to_free_swap() instead, or on swapoff+swapon. A, faults into do_swap_page(): does page1 = lookup_swap_cache(swap1) and comes through the lock_page(page1). B, a racing thread of the same process, faults on the same address: does page1 = lookup_swap_cache(swap1) and now waits in lock_page(page1), but for whatever reason is unlucky not to get the lock any time soon. A carries on through do_swap_page(), a write fault, but cannot reuse the swap page1 (another reference to swap1). Unlocks the page1 (but B doesn't get it yet), does COW in do_wp_page(), page2 now in that pte. C, perhaps the parent of A+B, comes in and write faults the same swap page1 into its mm, reuse_swap_page() succeeds this time, swap1 is freed. kswapd comes in after some time (B still unlucky) and swaps out some pages from A+B and C: it allocates the original swap1 to page2 in A+B, and some other swap2 to the original page1 now in C. But does not immediately free page1 (actually it couldn't: B holds a reference), leaving it in swap cache for now. B at last gets the lock on page1, hooray! Is PageSwapCache(page1)? Yes. Is pte_same(*page_table, orig_pte)? Yes, because page2 has now been given the swap1 which page1 used to have. So B proceeds to insert page1 into A+B's page_table, though its content now belongs to C, quite different from what A wrote there. B ought to have checked that page1's swap was still swap1.

494486a | Al Viro | 18 September 2010, 12:42:27 UTC | alpha: deal with multiple simultaneously pending signals Unlike the other targets, alpha sets _one_ sigframe and buggers off until the next syscall/interrupt, even if more signals are pending. It leads to quite a few unpleasant inconsistencies, starting with SIGSEGV potentially arriving not where it should and including e.g. mess with sigsuspend(); consider two pending signals blocked until sigsuspend() unblocks them. We pick the first one; then, if we are hit by interrupt while in the handler, we process the second one as well. If we are not, and if no syscalls had been made, we get out of the first handler and leave the second signal pending; normally sigreturn() would've picked it anyway, but here it starts with restoring the original mask and voila - the second signal is blocked again. On everything else we get both delivered consistently. It's actually easy to fix; the only thing to watch out for is prevention of double syscall restart. Fortunately, the idea I've nicked from arm fix by rmk works just fine... Testcase demonstrating the behaviour in question; on alpha we get one or both flags set (usually one), on everything else both are always set. #include <signal.h> #include <stdio.h> int had1, had2; void f1(int sig) { had1 = 1; } void f2(int sig) { had2 = 1; } main() { sigset_t set1, set2; sigemptyset(&set1); sigemptyset(&set2); sigaddset(&set2, 1); sigaddset(&set2, 2); signal(1, f1); signal(2, f2); sigprocmask(SIG_SETMASK, &set2, NULL); raise(1); raise(2); sigsuspend(&set1); printf("had1:%d had2:%d\n", had1, had2); } Tested-by: Michael Cree <mcree@orcon.net.nz> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Matt Turner <mattst88@gmail.com> | 19 September 2010, 03:08:29 UTC |
5329363 | Al Viro | 18 September 2010, 12:41:16 UTC | alpha: fix a 14 years old bug in sigreturn tracing The way sigreturn() is implemented on alpha breaks PTRACE_SYSCALL, all way back to 1.3.95 when alpha has grown PTRACE_SYSCALL support. What happens is direct return to ret_from_syscall, in order to bypass mangling of a3 (error indicator) and prevent other mutilations of registers (e.g. by syscall restart). That's fine, but... the entire TIF_SYSCALL_TRACE codepath is kept separate on alpha and post-syscall stopping/notifying the tracer is after the syscall. And the normal path we are forcibly switching to doesn't have it. So we end up with *one* stop in traced sigreturn() vs. two in other syscalls. And yes, strace is visibly broken by that; try to strace the following #include <signal.h> #include <stdio.h> void f(int sig) {} main() { signal(SIGHUP, f); raise(SIGHUP); write(1, "eeeek\n", 6); } and watch the show. The close(1) = 405 in the end of strace output is coming from return value of write() (6 == __NR_close on alpha) and syscall number of exit_group() (__NR_exit_group == 405 there). The fix is fairly simple - the only thing we end up missing is the call of syscall_trace() and we can tell whether we'd been called from the SYSCALL_TRACE path by checking ra value. Since we are setting the switch_stack up (that's what sys_sigreturn() does), we have the right environment for calling syscall_trace() - just before we call undo_switch_stack() and return. Since undo_switch_stack() will overwrite s0 anyway, we can use it to store the result of "has it been called from SYSCALL_TRACE path?" check. The same thing applies in rt_sigreturn().

392fb6e | Al Viro | 18 September 2010, 12:40:07 UTC | alpha: unb0rk sigsuspend() and rt_sigsuspend() Old code used to set regs->r0 and regs->r19 to force the right return value. Leaving that after switch to ERESTARTNOHAND was a Bad Idea(tm), since now that screws the restart - if we hit the case when get_signal_to_deliver() returns 0, we will step back to syscall insn, with v0 set to EINTR and a3 to 1. The latter won't matter, since EINTR is 4, aka __NR_write. Testcase: #include <signal.h> #define _GNU_SOURCE #include <unistd.h> #include <sys/syscall.h> main() { sigset_t mask; sigemptyset(&mask); sigaddset(&mask, SIGCONT); sigprocmask(SIG_SETMASK, &mask, NULL); kill(0, SIGCONT); syscall(__NR_sigsuspend, 1, "b0rken\n", 7); } results on alpha in immediate message to stdout... Fix is obvious; moreover, since we don't need regs anymore, we can switch to normal prototypes for these guys and lose the wrappers. Even better, rt_sigsuspend() is identical to generic version in kernel/signal.c now.

653d48b | Al Viro | 17 September 2010, 13:34:39 UTC | arm: fix really nasty sigreturn bug If a signal hits us outside of a syscall and another gets delivered when we are in sigreturn (e.g. because it had been in sa_mask for the first one and got sent to us while we'd been in the first handler), we have a chance of returning from the second handler to location one insn prior to where we ought to return. If r0 happens to contain -513 (-ERESTARTNOINTR), sigreturn will get confused into doing restart syscall song and dance. Incredible joy to debug, since it manifests as random, infrequent and very hard to reproduce double execution of instructions in userland code... The fix is simple - mark it "don't bother with restarts" in wrapper, i.e. set r8 to 0 in sys_sigreturn and sys_rt_sigreturn wrappers, suppressing the syscall restart handling on return from these guys. They can't legitimately return a restart-worthy error anyway.

If an array with 1.x metadata is assembled with the last disk missing, md doesn't properly record the fact that the disk was missing. This is unlikely to cause a real problem as the event count will be different to the count on the missing disk so it won't be included in the array. However it could still cause confusion.

Now that we depend on md_update_sb to clear variable bits in mddev->flags (rather than trying not to set them) it is important to always call md_update_sb when appropriate. md_check_recovery has this job but explicitly avoids it for ->external metadata arrays. This is not longer appropraite, or needed. However we do want to avoid taking the mddev lock if only MD_CHANGE_PENDING is set as that is not cleared by md_update_sb for external-metadata arrays.

Hence let make descend into drivers/firewire/ also if that option is off. The stand-alone driver drivers/ieee1394/init_ohci1394_dma* will soon be moved into drivers/firewire/ too and will require the same makefile fix. Side effect: As mentioned in https://bugzilla.novell.com/show_bug.cgi?id=586172#c24 this influences the order in which either firewire-ohci or ohci1394 is going to be bound to an OHCI-1394 controller in case of a modular build of both drivers if no modprobe blacklist entries are configured. However, a user of such a setup cannot expect deterministic behavior anyway. The Kconfig help and the migration guide at ieee1394.wiki.kernel.org recommend blacklist entries when a dual IEEE 1394 stack build is being used.

fe725d4 | Alex Deucher | 14 September 2010, 14:10:47 UTC | drm/radeon/kms: only warn on mipmap size checks in r600 cs checker (v2) The texture base address registers are in units of 256 bytes. The original CS checker treated these offsets as bytes, so the original check was wrong. I fixed the units in a patch during the 2.6.36 cycle, but this ended up breaking some existing userspace (probably due to a bug in either userspace texture allocation or the drm texture mipmap checker). So for now, until we come up with a better fix, just warn if the mipmap size it too large. This will keep existing userspace working and it should be just as safe as before when we were checking the wrong units. These are GPU MC addresses, so if they fall outside of the VRAM or GART apertures, they end up at the GPU default page, so this should be safe from a security perspective. v2: Just disable the warning. It just spams the log and there's nothing the user can do about it.
