6db40cf Miklos Szeredi 09 June 2010, 07:27:57 UTC pipe: fix check in "set size" fcntl As it stands this check compares the number of pages to the page size. This makes no sense and makes the fcntl fail in almost any sane case. Fix it by checking if nr_pages is not zero (it can become zero only if arg is too big and round_pipe_size() overflows).

a7f5378 David Howells 09 June 2010, 18:52:22 UTC FRV: Reinstate null behaviour for the GDB remote protocol 'p' command Reinstate the null behaviour that the in-kernel gdbstub had for the GDB remote protocol 'p' command (retrieve a single register value) prior to commit 7ca8b9c0dafd ("frv: extend gdbstub to support more features of gdb"). Before that, the 'p' command just returned an empty reply, which causes gdb to then go and use the 'g' command. However, since that commit, the 'p' command returns an error string, which causes gdb to abort its connection to the target. Not all gdb versions are affected, some use try 'g' first, and if that works, don't bother with 'p', and so don't see the error.

d87815c Dave Chinner 09 June 2010, 00:37:20 UTC writeback: limit write_cache_pages integrity scanning to current EOF sync can currently take a really long time if a concurrent writer is extending a file. The problem is that the dirty pages on the address space grow in the same direction as write_cache_pages scans, so if the writer keeps ahead of writeback, the writeback will not terminate until the writer stops adding dirty pages. For a data integrity sync, we only need to write the pages dirty at the time we start the writeback, so we can stop scanning once we get to the page that was at the end of the file at the time the scan started. This will prevent operations like copying a large file preventing sync from completing as it will not write back pages that were dirtied after the sync was started. This does not impact the existing integrity guarantees, as any dirty page (old or new) within the EOF range at the start of the scan will still be captured. This patch will not prevent sync from blocking on large writes into holes. That requires more complex intervention while this patch only addresses the common append-case of this sync holdoff.

0b56492 Dave Chinner 09 June 2010, 00:37:18 UTC writeback: pay attention to wbc->nr_to_write in write_cache_pages If a filesystem writes more than one page in ->writepage, write_cache_pages fails to notice this and continues to attempt writeback when wbc->nr_to_write has gone negative - this trace was captured from XFS: wbc_writeback_start: towrt=1024 wbc_writepage: towrt=1024 wbc_writepage: towrt=0 wbc_writepage: towrt=-1 wbc_writepage: towrt=-5 wbc_writepage: towrt=-21 wbc_writepage: towrt=-85 This has adverse effects on filesystem writeback behaviour. write_cache_pages() needs to terminate after a certain number of pages are written, not after a certain number of calls to ->writepage are made. This is a regression introduced by 17bc6c30cf6bfffd816bdc53682dd46fc34a2cf4 ("vfs: Add no_nrwrite_index_update writeback control flag"), but cannot be reverted directly due to subsequent bug fixes that have gone in on top of it.

The former makes it hard to debug, while the latter later causes a warning in cfg80211 when, as will typically be the case, association timed out. This warning was reported by many, e.g. in https://bugzilla.kernel.org/show_bug.cgi?id=15981, but I couldn't initially pinpoint it.

This helps find bad usages such as dereferences after the unmap, or overflow into the adjacent fixmap areas. But this debugging aid is completely bypassed when a kmap for the same page already exists as the kmap is reused instead. ON VIVT systems we have no choice but to reuse that kmap due to cache coherency issues, but on non VIVT systems we should always force the fixmap usage when debugging is active.

f6ab91a Peter Zijlstra 04 June 2010, 13:18:01 UTC perf: Fix signed comparison in perf_adjust_period() Frederic reported that frequency driven swevents didn't work properly and even caused a division-by-zero error. It turns out there are two bugs, the division-by-zero comes from a failure to deal with that in perf_calculate_period(). The other was more interesting and turned out to be a wrong comparison in perf_adjust_period(). The comparison was between an s64 and u64 and got implicitly converted to an unsigned comparison. The problem is that period_left is typically < 0, so it ended up being always true. Cure this by making the local period variables s64.

b62e948 Dave Airlie 08 June 2010, 00:42:28 UTC drm/radeon: don't poll tv dac if crtc2 is in use. So when we added output polling, we'd suddenly use this code more often, and the fact that it always takes over crtc2 and messes with it during probing isn't what we really want to be happening. A more complete fix would to change it to use whatever crtc was free at the time, but for now lets stay simple and just don't poll if crtc2 is already in use. Although a more correct fix was found I suspect we should do this as well, until we get a chance to readdres the tv out polling issues.

035320d Eric Dumazet 06 June 2010, 23:48:40 UTC ipmr: dont corrupt lists ipmr_rules_exit() and ip6mr_rules_exit() free a list of items, but forget to properly remove these items from list. List head is not changed and still points to freed memory. This can trigger a fault later when icmpv6_sk_exit() is called. Fix is to either reinit list, or use list_del() to properly remove items from list before freeing them. bugzilla report : https://bugzilla.kernel.org/show_bug.cgi?id=16120 Introduced by commit d1db275dd3f6e4 (ipv6: ip6mr: support multiple tables) and commit f0ad0860d01e (ipv4: ipmr: support multiple tables) Reported-by: Alex Zhavnerchik <alex.vizor@gmail.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

Problem is that MTU might be set larger than 1500 and asix fails to work correctly with VLAN tagged packets. The check should be 'dev->net->mtu + ETH_HLEN' instead. Tested with AX88772.

386f40c Linus Torvalds 07 June 2010, 03:44:04 UTC Revert "tty: fix a little bug in scrup, vt.c" This reverts commit 962400e8fd29981a7b166e463dd143b6ac6a3e76, which was entirely bogus. The code used to multiply the character offset by "vc->vc_cols", and that's actually correct, because 'd' itself is an 'unsigned short'. So the pointer arithmetic already takes the size of a VGA character into account. Changing it to use vc_size_row (which is just "vc_cols" shifted up to take the size of the character into account) ends up multiplying with the VGA character size twice. This got reported as bugs for various other subsystems, because what it actually results in is writing the 16-bit vc_video_erase_char pattern (usually 0x0720: 0x07 is the default attribute, 0x20 is ASCII space) into some random other allocation. So Markus ended up reporting this as a ext4 bug, while to Torsten Kaiser it looked like a problem with KMS or libata. Jeff Chua saw it in different places. And finally - Justin Mattock had slab poisoning enabled, and saw it as a slab poison overwritten. And bisected and reverted this to verify the buggy commit.

024a07b Timo Teräs 06 June 2010, 22:38:47 UTC r8169: fix random mdio_write failures Some configurations need delay between the "write completed" indication and new write to work reliably. Realtek driver seems to use longer delay when polling the "write complete" bit, so it waits long enough between writes with high probability (but could probably break too). This patch adds a new udelay to make sure we wait unconditionally some time after the write complete indication. This caused a regression with XID 18000000 boards when the board specific phy configuration writing many mdio registers was added in commit 2e955856ff (r8169: phy init for the 8169scd). Some of the configration mdio writes would almost always fail, and depending on failure might leave the PHY in non-working state.

7d47618 Emmanuel Grumbach 23 May 2010, 07:14:08 UTC iwlwifi: move sysfs_create_group to post request firmware Move the sysfs_create_group to iwl_ucode_callback after we have safely got the firmware. The motivation to do this comes from a warning from lockdep which detected that we request priv->mutex while holding s_active during a sysfs request (show_statistics in the example copy pasted). The reverse order exists upon request_firmware: request_firmware which is a sysfs operation that requires s_active is run under priv->mutex. This ensures that we don't get sysfs request before we finish to request the firmware, avoiding this deadlock. ======================================================= [ INFO: possible circular locking dependency detected ] ------------------------------------------------------- cat/2595 is trying to acquire lock: (&priv->mutex){+.+.+.}, at: [<facfa598>] show_statistics+0x48/0x100 [iwlagn] but task is already holding lock: (s_active){++++.+}, at: [<c0580ebd>] sysfs_get_active_two+0x1d/0x50 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (s_active){++++.+}: [<c0489b74>] __lock_acquire+0xc44/0x1230 [<c048a1ed>] lock_acquire+0x8d/0x110 [<c0581499>] sysfs_addrm_finish+0xe9/0x180 [<c057f64a>] sysfs_hash_and_remove+0x4a/0x80 [<c05829d4>] sysfs_remove_group+0x44/0xd0 [<c0714b75>] dpm_sysfs_remove+0x15/0x20 [<c070dac8>] device_del+0x38/0x170 [<c070dc1e>] device_unregister+0x1e/0x60 [<c071838d>] _request_firmware+0x29d/0x550 [<c07186c7>] request_firmware+0x17/0x20 [<fad01bf1>] iwl_mac_start+0xb1/0x1230 [iwlagn] [<fa46ba06>] ieee80211_open+0x436/0x6f0 [mac80211] [<c0808cd2>] dev_open+0x92/0xf0 [<c0808b2b>] dev_change_flags+0x7b/0x190 [<c08148e8>] do_setlink+0x178/0x3b0 [<c0815169>] rtnl_setlink+0xf9/0x130 [<c081453b>] rtnetlink_rcv_msg+0x1bb/0x1f0 [<c0827ce6>] netlink_rcv_skb+0x86/0xa0 [<c081436c>] rtnetlink_rcv+0x1c/0x30 [<c08279c3>] netlink_unicast+0x263/0x290 [<c0828768>] netlink_sendmsg+0x1c8/0x2a0 [<c07f85fd>] sock_sendmsg+0xcd/0x100 [<c07f964d>] sys_sendmsg+0x15d/0x290 [<c07f9e6b>] sys_socketcall+0xeb/0x2a0 [<c040ad9f>] sysenter_do_call+0x12/0x38 -> #0 (&priv->mutex){+.+.+.}: [<c0489f84>] __lock_acquire+0x1054/0x1230 [<c048a1ed>] lock_acquire+0x8d/0x110 [<c08bb358>] __mutex_lock_common+0x58/0x470 [<c08bb84a>] mutex_lock_nested+0x3a/0x50 [<facfa598>] show_statistics+0x48/0x100 [iwlagn] [<c070d219>] dev_attr_show+0x29/0x50 [<c057fecd>] sysfs_read_file+0xdd/0x190 [<c052880f>] vfs_read+0x9f/0x190 [<c0528d22>] sys_read+0x42/0x70 [<c040ad9f>] sysenter_do_call+0x12/0x38 other info that might help us debug this: 3 locks held by cat/2595: #0: (&buffer->mutex){+.+.+.}, at: [<c057fe25>] sysfs_read_file+0x35/0x190 #1: (s_active){++++.+}, at: [<c0580ecd>] sysfs_get_active_two+0x2d/0x50 #2: (s_active){++++.+}, at: [<c0580ebd>] sysfs_get_active_two+0x1d/0x50 stack backtrace: Pid: 2595, comm: cat Not tainted 2.6.33-tp-rc4 #2 Call Trace: [<c08b99ab>] ? printk+0x1d/0x22 [<c0487752>] print_circular_bug+0xc2/0xd0 [<c0489f84>] __lock_acquire+0x1054/0x1230 [<c0478d81>] ? sched_clock_cpu+0x121/0x180 [<c048a1ed>] lock_acquire+0x8d/0x110 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<c08bb358>] __mutex_lock_common+0x58/0x470 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<c08bb84a>] mutex_lock_nested+0x3a/0x50 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<facfa598>] show_statistics+0x48/0x100 [iwlagn] [<c0580cf9>] ? sysfs_get_active+0x69/0xb0 [<facfa550>] ? show_statistics+0x0/0x100 [iwlagn] [<c070d219>] dev_attr_show+0x29/0x50 [<c057fecd>] sysfs_read_file+0xdd/0x190 [<c05ff314>] ? security_file_permission+0x14/0x20 [<c0528242>] ? rw_verify_area+0x62/0xd0 [<c052880f>] vfs_read+0x9f/0x190 [<c047745b>] ? up_read+0x1b/0x30 [<c057fdf0>] ? sysfs_read_file+0x0/0x190 [<c04af3b4>] ? audit_syscall_entry+0x1f4/0x220 [<c0528d22>] sys_read+0x42/0x70 [<c040ad9f>] sysenter_do_call+0x12/0x38 Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> 06 June 2010, 06:02:39 UTC
