2009-01-29epoll: drop max_user_instances and rely only on max_user_watchesDavide Libenzi
Linus suggested to put limits where the money is, and max_user_watches already does that w/out the need of max_user_instances. That has the advantage to mitigate the potential DoS while allowing pretty generous default behavior. Allowing top 4% of low memory (per user) to be allocated in epoll watches, we have: LOMEM MAX_WATCHES (per user) 512MB ~178000 1GB ~356000 2GB ~712000 A box with 512MB of lomem, will meet some challenge in hitting 180K watches, socket buffers math teaches us. No more max_user_instances limits then.

2009-01-29alpha: fix the BUG() macroIvan Kokshaysky
The commit "alpha: teach the compiler that BUG doesn't return" (ed6b9b97f42c091630335bfb71a2931e6f86388b) moved the asm code into inline function which takes __FILE__ and __LINE__ as arguments. This violates asm constrains there ("i" - an immediate operand with constant value), so that compile may result in warning or error, depending on compiler version. Just adding an infinite loop to the BUG() is sufficient.

2009-01-29memcg: get/put parents at create/freeDaisuke Nishimura
The lifetime of struct cgroup and struct mem_cgroup is different and mem_cgroup has its own reference count for handling references from swap_cgroup. This causes strange problem that the parent mem_cgroup dies while child mem_cgroup alive, and this problem causes a bug in case of use_hierarchy==1 because res_counter_uncharge climbs up the tree.

2009-01-29Fix OOPS in mmap_region() when merging adjacent VM_LOCKED file segmentsLinus Torvalds
As of commit ba470de43188cdbff795b5da43a1474523c6c2fb ("map: handle mlocked pages during map, remap, unmap") we now use the 'vma' variable at the end of mmap_region() to handle the page-in of newly mapped mlocked pages. However, if we merged adjacent vma's together, the vma we're using may be stale. We historically consciously avoided using it after the merge operation, but that got overlooked when redoing the locked page handling. This commit simplifies mmap_region() by doing any vma merges early, avoiding the issue entirely, and 'vma' will always be valid. As pointed out by Hugh Dickins, this depends on any drivers that change the page offset of flags to have set one of the VM_SPECIAL bits (so that they cannot trigger the early merge logic), but that's true in general.

2009-01-29gianfar: Fix Wake-on-LAN supportAnton Vorontsov
commit 0f0ca340e57bd7446855fefd07a64249acf81223 ("phy: power management support") caused a regression in the gianfar driver. Now phylib turns off PHY power during suspend, and thus WOL doesn't work anymore. This patch workarounds the issue by enabling wakeup in the MDIO device, i.e. just restores the old behaviour for the gianfar driver. Note that this way all PHYs on a given MDIO bus won't be turned off during suspend, which isn't good from the power saving point of view. A proper, per netdevice wakeup management support will need a bit reworked phylib suspend/resume logic. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.

These definitions are always needed if debug is enabled at compile time (independently of DEBUG_FS being or not enabled), so moving them to a file that is always compiled fixes the issue.

This caused the kernel panic. if (abs_offset < block_limit) { - *data = st->cur_skb->data + abs_offset; + *data = st->cur_skb->data + (abs_offset - st->stepped_offset); I enabled the debug_tcp and with a few printks found that the code did not go to the next_skb label and could find that the sequence being followed was this - It hit this if condition - if (st->cur_skb->next) { st->cur_skb = st->cur_skb->next; st->frag_idx = 0; goto next_skb; And so, now the st pointer is shifted to the next skb whereas actually it should have hit the second else if first since the data is in the frag_list. else if (st->root_skb == st->cur_skb && skb_shinfo(st->root_skb)->frag_list) { st->cur_skb = skb_shinfo(st->root_skb)->frag_list; goto next_skb; } Reversing the two conditions the attached patch fixes the issue for me on top of Herbert's patches.

as per https://bugs.launchpad.net/bugs/294391. These got one sample of each iPod generation going. However there still occurred I/O stalls with the 3rd generation iPod which remain undiagnosed at the time of this writing.

2009-01-29firewire: sbp2: add workarounds for 2nd and 3rd generation iPodsStefan Richter
According to https://bugs.launchpad.net/bugs/294391 - 3rd generation iPods need the "fix capacity" workaround after all (apparently they crash after the last sector was accessed), - 2nd generation iPods need the "128 kB maximum request size" workaround. Alas both iPod generations feature the same model ID in the config ROM, hence we can only define a shared quirks list entry for them. Luckily the fix capacity workaround did not show a negative effect in Jarod's tests with 2nd gen. iPod. A side note: Apple computers in target mode (or at least an x86 Mac mini) don't have firmware_version and model_id, hence none of the iPod quirks list entries is active for them.
