e7b526b | Chris Wilson | 02 June 2010, 07:30:48 UTC | drm/i915: Move non-phys cursors into the GTT Cursors need to be in the GTT domain when being accessed by the GPU. Previously this was a fortuitous byproduct of userspace using pwrite() to upload the image data into the cursor. The redundant clflush was removed in commit 9b8c4a and so the image was no longer being flushed out of the caches into main memory. One could also devise a scenario where the cursor was rendered by the GPU, prior to being attached as the cursor, resulting in similar corruption due to the missing MI_FLUSH.

9bea7f2 | Rusty Russell | 05 June 2010, 17:17:37 UTC | module: fix bne2 "gave up waiting for init of module libcrc32c" Problem: it's hard to avoid an init routine stumbling over a request_module these days. And it's not clear it's always a bad idea: for example, a module like kvm with dynamic dependencies on kvm-intel or kvm-amd would be neater if it could simply request_module the right one. In this particular case, it's libcrc32c: libcrc32c_mod_init crypto_alloc_shash crypto_alloc_tfm crypto_find_alg crypto_alg_mod_lookup crypto_larval_lookup request_module If another module is waiting inside resolve_symbol() for libcrc32c to finish initializing (ie. bne2 depends on libcrc32c) then it does so holding the module lock, and our request_module() can't make progress until that is released. Waiting inside resolve_symbol() without the lock isn't all that hard: we just need to pass the -EBUSY up the call chain so we can sleep where we don't hold the lock. Error reporting is a bit trickier: we need to copy the name of the unfinished module before releasing the lock. Other notes: 1) This also fixes a theoretical issue where a weak dependency would allow symbol version mismatches to be ignored. 2) We rename use_module to ref_module to make life easier for the only external user (the out-of-tree ksplice patches).

be593f4 | Rusty Russell | 05 June 2010, 17:17:37 UTC | module: verify_export_symbols under the lock It disabled preempt so it was "safe", but nothing stops another module slipping in before this module is added to the global list now we don't hold the lock the whole time. So we check this just after we check for duplicate modules, and just before we put the module in the global list. (find_symbol finds symbols in coming and going modules, too).

3bafeb6 | Linus Torvalds | 05 June 2010, 17:17:36 UTC | module: move find_module check to end I think Rusty may have made the lock a bit _too_ finegrained there, and didn't add it to some places that needed it. It looks, for example, like PATCH 1/2 actually drops the lock in places where it's needed ("find_module()" is documented to need it, but now load_module() didn't hold it at all when it did the find_module()). Rather than adding a new "module_loading" list, I think we should be able to just use the existing "modules" list, and just fix up the locking a bit. In fact, maybe we could just move the "look up existing module" a bit later - optimistically assuming that the module doesn't exist, and then just undoing the work if it turns out that we were wrong, just before adding ourselves to the list.

7567650 | Rusty Russell | 05 June 2010, 17:17:36 UTC | module: make locking more fine-grained. Kay Sievers <kay.sievers@vrfy.org> reports that we still have some contention over module loading which is slowing boot. Linus also disliked a previous "drop lock and regrab" patch to fix the bne2 "gave up waiting for init of module libcrc32c" message. This is more ambitious: we only grab the lock where we need it.

80a3d1b | Rusty Russell | 05 June 2010, 17:17:36 UTC | module: move sysfs exposure to end of load_module This means a little extra work, but is more logical: we don't put anything in sysfs until we're about to put the module into the global list an parse its parameters. This also gives us a logical place to put duplicate module detection in the next patch. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> | 05 June 2010, 01:47:36 UTC |

2c02dfe | Linus Torvalds | 31 May 2010, 19:19:37 UTC | module: Make the 'usage' lists be two-way When adding a module that depends on another one, we used to create a one-way list of "modules_which_use_me", so that module unloading could see who needs a module. It's actually quite simple to make that list go both ways: so that we not only can see "who uses me", but also see a list of modules that are "used by me". In fact, we always wanted that list in "module_unload_free()": when we unload a module, we want to also release all the other modules that are used by that module. But because we didn't have that list, we used to first iterate over all modules, and then iterate over each "used by me" list of that module. By making the list two-way, we simplify module_unload_free(), and it allows for some trivial fixes later too.

ca55158 | Eric Dumazet | 03 June 2010, 09:03:58 UTC | rps: tcp: fix rps_sock_flow_table table updates I believe a moderate SYN flood attack can corrupt RFS flow table (rps_sock_flow_table), making RPS/RFS much less effective. Even in a normal situation, server handling short lived sessions suffer from bad steering for the first data packet of a session, if another SYN packet is received for another session. We do following action in tcp_v4_rcv() : sock_rps_save_rxhash(sk, skb->rxhash); We should _not_ do this if sk is a LISTEN socket, as about each packet received on a LISTEN socket has a different rxhash than previous one. -> RPS_NO_CPU markers are spread all over rps_sock_flow_table. Also, it makes sense to protect sk->rxhash field changes with socket lock (We currently can change it even if user thread owns the lock and might use rxhash) This patch moves sock_rps_save_rxhash() to a sock locked section, and only for non LISTEN sockets.

683eb94 | Cory Maccarrone | 04 June 2010, 21:15:07 UTC | omap: remove BUG_ON for disabled interrupts Remove a BUG_ON for when interrupts are disabled during an MMC request. During boot, interrupts can be disabled when a request is made, causing this bug to be triggered. In reality, there's no reason this should halt the kernel, as the driver has proved reliable in spite of disabled interrupts, and additionally, there's nothing in this code that would require interrupts to be enabled. The only setup I've managed to make it trigger on is on the HTC Herald during bootup when the driver is built into the kernel (mostly because that's all I have). I believe it's related to the fact that on bootup I get many timeout errors on "CMD5" while initializing the card. Each CMD5 timeout triggers that bug (I changed it to a WARN_ON to get it to boot in) due to the fact that part of the timeout code involves sending the request again. With interrupts turned off, that BUG would be triggered.

But the above patch changed to "return nr_reclaimed if .....". Oh, That forgot nr_reclaimed may be 0 if priority==0 reclaim failure. And Johannes's patch 0aeb2339e54e ("vmscan: remove all_unreclaimable scan control") made it more corrupt. Originally, priority==0 reclaim failure on memcg return 0, but this patch changed to return 1. It totally confused memcg. This patch fixes it completely.

485d527 | Oleg Nesterov | 04 June 2010, 21:14:58 UTC | sys_personality: change sys_personality() to accept "unsigned int" instead of u_long task_struct->pesonality is "unsigned int", but sys_personality() paths use "unsigned long pesonality". This means that every assignment or comparison is not right. In particular, if this argument does not fit into "unsigned int" __set_personality() changes the caller's personality and then sys_personality() returns -EINVAL. Turn this argument into "unsigned int" and avoid overflows. Obviously, this is the user-visible change, we just ignore the upper bits. But this can't break the sane application. There is another thing which can confuse the poorly written applications. User-space thinks that this syscall returns int, not long. This means that the returned value can be negative and look like the error code. But note that libc won't be confused and thus errno won't be set, and with this patch the user-space can never get -1 unless sys_personality() really fails. And, most importantly, the negative RET != -1 is only possible if that app previously called personality(RET).

This area is all still rather buggy in different ways in a lot of filesystems and needs a cleanup and audit (ideally the vfs will provide a simple attribute or call to direct all filesystems exactly which attributes to change).
