2009-12-01SLOW_WORK: Fix the CONFIG_MODULES=n caseDavid Howells
Commits 3d7a641 ("SLOW_WORK: Wait for outstanding work items belonging to a module to clear") introduced some code to make sure that all of a module's slow-work items were complete before that module was removed, and commit 3bde31a ("SLOW_WORK: Allow a requeueable work item to sleep till the thread is needed") further extended that, breaking it in the process if CONFIG_MODULES=n: CC kernel/slow-work.o kernel/slow-work.c: In function 'slow_work_execute': kernel/slow-work.c:313: error: 'slow_work_thread_processing' undeclared (first use in this function) kernel/slow-work.c:313: error: (Each undeclared identifier is reported only once kernel/slow-work.c:313: error: for each function it appears in.) kernel/slow-work.c: In function 'slow_work_wait_for_items': kernel/slow-work.c:950: error: 'slow_work_unreg_sync_lock' undeclared (first use in this function) kernel/slow-work.c:951: error: 'slow_work_unreg_wq' undeclared (first use in this function) kernel/slow-work.c:961: error: 'slow_work_unreg_work_item' undeclared (first use in this function) kernel/slow-work.c:974: error: 'slow_work_unreg_module' undeclared (first use in this function) kernel/slow-work.c:977: error: 'slow_work_thread_processing' undeclared (first use in this function) make[1]: *** [kernel/slow-work.o] Error 1 Fix this by: (1) Extracting the bits of slow_work_execute() that are contingent on CONFIG_MODULES, and the bits that should be, into inline functions and placing them into the #ifdef'd section that defines the relevant variables and adding stubs for moduleless kernels. This allows the removal of some #ifdefs. (2) #ifdef'ing out the contents of slow_work_wait_for_items() in moduleless kernels. The four functions related to handling module unloading synchronisation (and their associated variables) could be offloaded into a separate .c file, but each function is only used once and three of them are tiny, so doing so would prevent them from being inlined.

2009-11-30Alpha: Rearrange thread info flags fixing two regressionsMichael Cree
The removal of the TIF_NOTIFY_RESUME flag, commit a583f1b54249b "remove unused TIF_NOTIFY_RESUME flag," resulted in incorrect setting of the unaligned access control flags by the prctl syscall. The re-addition of the TIF_NOTIFY_RESUME flag, commit d0420c83f39f "KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures [try #6]" further caused problems, namely incorrect operands to assembler code as evidenced by: AS arch/alpha/kernel/entry.o arch/alpha/kernel/entry.S: Assembler messages: arch/alpha/kernel/entry.S:326: Warning: operand out of range (0x0000000000000406 is not between 0x0000000000000000 and 0x00000000000000ff) Both regressions fixed by (1) rearranging TIF_NOTIFY_RESUME flag to be in lower 8 bits of the thread info flags, and (2) making sure that ALPHA_UAC_SHIFT matches the rearrangement of the thread info flags.

Code was added to mm/higmem.c that depends on several kmap types that powerpc does not support. We add dummy invalid definitions for KM_NMI, KM_NM_PTE, and KM_IRQ_PTE. According to list discussion, this fix should not be needed anymore starting with 2.6.33. The code is commented to this effect so hopefully we will remember to remove this.

2009-11-30jffs2: Fix memory corruption in jffs2_read_inode_range()David Woodhouse
In 2.6.23 kernel, commit a32ea1e1f925399e0d81ca3f7394a44a6dafa12c ("Fix read/truncate race") fixed a race in the generic code, and as a side effect, now do_generic_file_read() can ask us to readpage() past the i_size. This seems to be correctly handled by the block routines (e.g. block_read_full_page() fills the page with zeroes in case if somebody is trying to read past the last inode's block). JFFS2 doesn't handle this; it assumes that it won't be asked to read pages which don't exist -- and thus that there will be at least _one_ valid 'frag' on the page it's being asked to read. It will fill any holes with the following memset: memset(buf, 0, min(end, frag->ofs + frag->size) - offset); When the 'closest smaller match' returned by jffs2_lookup_node_frag() is actually on a previous page and ends before 'offset', that results in: memset(buf, 0, <huge unsigned negative>); Hopefully, in most cases the corruption is fatal, and quickly causing random oopses, like this: root@10.0.0.4:~/ltp-fs-20090531# ./testcases/kernel/fs/ftest/ftest01 Unable to handle kernel paging request for data at address 0x00000008 Faulting instruction address: 0xc01cd980 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c01cd980] rb_insert_color+0x38/0x184 LR [c0043978] enqueue_hrtimer+0x88/0xc4 Call Trace: [c6c63b60] [c004f9a8] tick_sched_timer+0xa0/0xe4 (unreliable) [c6c63b80] [c0043978] enqueue_hrtimer+0x88/0xc4 [c6c63b90] [c0043a48] __run_hrtimer+0x94/0xbc [c6c63bb0] [c0044628] hrtimer_interrupt+0x140/0x2b8 [c6c63c10] [c000f8e8] timer_interrupt+0x13c/0x254 [c6c63c30] [c001352c] ret_from_except+0x0/0x14 --- Exception: 901 at memset+0x38/0x5c LR = jffs2_read_inode_range+0x144/0x17c [c6c63cf0] [00000000] (null) (unreliable) This patch fixes the issue, plus fixes all LTP tests on NAND/UBI with JFFS2 filesystem that were failing since 2.6.23 (seems like the bug above also broke the truncation).

2009-11-30mac80211: fix spurious delBA handlingJohannes Berg
Lennert Buytenhek noticed that delBA handling in mac80211 was broken and has remotely triggerable problems, some of which are due to some code shuffling I did that ended up changing the order in which things were done -- this was commit d75636ef9c1af224f1097941879d5a8db7cd04e5 Author: Johannes Berg <johannes@sipsolutions.net> Date: Tue Feb 10 21:25:53 2009 +0100 mac80211: RX aggregation: clean up stop session and other parts were already present in the original commit d92684e66091c0f0101819619b315b4bb8b5bcc5 Author: Ron Rindjunsky <ron.rindjunsky@intel.com> Date: Mon Jan 28 14:07:22 2008 +0200 mac80211: A-MPDU Tx add delBA from recipient support The first problem is that I moved a BUG_ON before various checks -- thereby making it possible to hit. As the comment indicates, the BUG_ON can be removed since the ampdu_action callback must already exist when the state is != IDLE. The second problem isn't easily exploitable but there's a race condition due to unconditionally setting the state to OPERATIONAL when a delBA frame is received, even when no aggregation session was ever initiated. All the drivers accept stopping the session even then, but that opens a race window where crashes could happen before the driver accepts it. Right now, a WARN_ON may happen with non-HT drivers, while the race opens only for HT drivers. For this case, there are two things necessary to fix it: 1) don't process spurious delBA frames, and be more careful about the session state; don't drop the lock 2) HT drivers need to be prepared to handle a session stop even before the session was really started -- this is true for all drivers (that support aggregation) but iwlwifi which can be fixed easily. The other HT drivers (ath9k and ar9170) are behaving properly already.

2009-11-30mac80211: fix two remote exploitsJohannes Berg
Lennert Buytenhek noticed a remotely triggerable problem in mac80211, which is due to some code shuffling I did that ended up changing the order in which things were done -- this was in commit d75636ef9c1af224f1097941879d5a8db7cd04e5 Author: Johannes Berg <johannes@sipsolutions.net> Date: Tue Feb 10 21:25:53 2009 +0100 mac80211: RX aggregation: clean up stop session The problem is that the BUG_ON moved before the various checks, and as such can be triggered. As the comment indicates, the BUG_ON can be removed since the ampdu_action callback must already exist when the state is OPERATIONAL. A similar code path leads to a WARN_ON in ieee80211_stop_tx_ba_session, which can also be removed.

2009-11-30b44: Fix wedge when using netconsole.David S. Miller
Fixes kernel bugzilla #14691 Due to the way netpoll works, it is perfectly legal to see NAPI already scheduled when new device events are pending in b44_interrupt(). So logging a message about it is wrong and in fact harmful. Based upon a patch by Andreas Mohr. Signed-off-by: David S. Miller <davem@davemloft.net>
