2010-09-17NFS: Clean up NFSROOT command line parsingChuck Lever1-9/+23
Clean up: To reduce confusion, rename nfs_root_name as nfs_root_parms, as this buffer contains more than just the name of the remote server. Introduce documenting comments around nfs_root_setup().

2010-08-29firewire: ohci: work around VIA and NEC PHY packet reception bugStefan Richter1-1/+9
VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write packet event codes for received PHY packets (or perhaps write evt_no_status, hard to tell). Work around it by overwriting the packet's ACK by ack_complete, so that upper layers that listen to PHY packet reception get to see these packets. (Also tested: TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643, JMicron JMB381 --- these do not exhibit this bug.) Clemens proposed a quirks flag for that, IOW whitelist known misbehaving controllers for this workaround. Though to me it seems harmless enough to enable for all controllers. The log_ar_at_event() debug log will continue to show the original status from the DMA unit.

This was added by commit 804af2cf6e7a ("[AGPGART] remove private page protection map") and is used in commit c07fbfd17e61 ("fbmem: VM_IO set, but not propagated") in the fbmem video driver, but the function doesn't exist on NOMMU, resulting in an undefined symbol at link time.

2010-08-28mm: fix hang on anon_vma->root->lockHugh Dickins1-3/+16
After several hours, kbuild tests hang with anon_vma_prepare() spinning on a newly allocated anon_vma's lock - on a box with CONFIG_TREE_PREEMPT_RCU=y (which makes this very much more likely, but it could happen without). The ever-subtle page_lock_anon_vma() now needs a further twist: since anon_vma_prepare() and anon_vma_fork() are liable to change the ->root of a reused anon_vma structure at any moment, page_lock_anon_vma() needs to check page_mapped() again before succeeding, otherwise page_unlock_anon_vma() might address a different root->lock.

2010-08-28ALSA: pcm: add more format namesDan Carpenter1-0/+6
There were some new formats added in commit 15c0cee6c809 "ALSA: pcm: Define G723 3-bit and 5-bit formats". That commit increased SNDRV_PCM_FORMAT_LAST as well. My concern is that there are a couple places which do: for (i = 0; i < SNDRV_PCM_FORMAT_LAST; i++) { if (dummy->pcm_hw.formats & (1ULL << i)) snd_iprintf(buffer, " %s", snd_pcm_format_name(i)); } I haven't tested these but it looks like if "i" were equal to SNDRV_PCM_FORMAT_G723_24 or higher then we might read past the end of the array.

2010-08-27net/ipv4: Eliminate kstrdup memory leakJulia Lawall1-2/+3
The string clone is only used as a temporary copy of the argument val within the while loop, and so it should be freed before leaving the function. The call to strsep, however, modifies clone, so a pointer to the front of the string is kept in saved_clone, to make it possible to free it. The sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ local idexpression x; expression E; identifier l; statement S; @@ *x= \(kasprintf\|kstrdup\)(...); ... if (x == NULL) S ... when != kfree(x) when != E = x if (...) { <... when != kfree(x) * goto l; ...> * return ...; } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2010-08-27fsnotify: drop two useless bools in the fnsotify main loopEric Paris1-8/+5
The fsnotify main loop has 2 bools which indicated if we processed the inode or vfsmount mark in that particular pass through the loop. These bool can we replaced with the inode_group and vfsmount_group variables and actually make the code a little easier to understand. Signed-off-by: Eric Paris <eparis@redhat.com>
2010-08-27fsnotify: fix list walk orderEric Paris1-6/+5
Marks were stored on the inode and vfsmonut mark list in order from highest memory address to lowest memory address. The code to walk those lists thought they were in order from lowest to highest with unpredictable results when trying to match up marks from each. It was possible that extra events would be sent to userspace when inode marks ignoring events wouldn't get matched with the vfsmount marks. This problem only affected fanotify when using both vfsmount and inode marks simultaneously. Signed-off-by: Eric Paris <eparis@redhat.com>
