This driver implements support for on-chip Embedded Tracing Macrocell and Embedded Trace Buffer. It allows to trigger tracing of kernel execution flow and exporting trace output to userspace via character device and a sysrq combo. Trace output can then be decoded by a fairly simple open source tool [1] which is already sufficient to get the idea of what the kernel is doing.

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.

由 David Woodhouse 提交于
In 2.6.23 kernel, commit a32ea1e1 ("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).

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 d75636ef 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 d92684e6 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.
