2008-11-23tracing/stack-tracer: avoid races accessing fileTörök Edwin
Impact: fix race vma->vm_file reference is only stable while holding the mmap_sem, so move usage of it to within the critical section. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-11-23tracing/stack-tracer: introduce CONFIG_USER_STACKTRACE_SUPPORTTörök Edwin
Impact: cleanup User stack tracing is just implemented for x86, but it is not x86 specific. Introduce a generic config flag, that is currently enabled only for x86. When other arches implement it, they will have to SELECT USER_STACKTRACE_SUPPORT. Signed-off-by: Török Edwin <edwintorok@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-11-23tracing: identify which executable object the userspace address belongs toTörök Edwin
Impact: modify+improve the userstacktrace tracing visualization feature Store thread group leader id, and use it to lookup the address in the process's map. We could have looked up the address on thread's map, but the thread might not exist by the time we are called. The process might not exist either, but if you are reading trace_pipe, that is unlikely. Example usage: mount -t debugfs nodev /sys/kernel/debug cd /sys/kernel/debug/tracing echo userstacktrace >iter_ctrl echo sym-userobj >iter_ctrl echo sched_switch >current_tracer echo 1 >tracing_enabled cat trace_pipe >/tmp/trace& .... run application ... echo 0 >tracing_enabled cat /tmp/trace You'll see stack entries like: /lib/libpthread-2.7.so[+0xd370] You can convert them to function/line using: addr2line -fie /lib/libpthread-2.7.so 0xd370 Or: addr2line -fie /usr/lib/debug/libpthread-2.7.so 0xd370 For non-PIC/PIE executables this won't work: a.out[+0x73b] You need to run the following: addr2line -fie a.out 0x40073b (where 0x400000 is the default load address of a.out) Signed-off-by: Török Edwin <edwintorok@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-11-23tracing: add support for userspace stacktraces in tracing/iter_ctrlTörök Edwin
Impact: add new (default-off) tracing visualization feature Usage example: mount -t debugfs nodev /sys/kernel/debug cd /sys/kernel/debug/tracing echo userstacktrace >iter_ctrl echo sched_switch >current_tracer echo 1 >tracing_enabled .... run application ... echo 0 >tracing_enabled Then read one of 'trace','latency_trace','trace_pipe'. To get the best output you can compile your userspace programs with frame pointers (at least glibc + the app you are tracing).

2008-11-21function tracing: fix wrong position computing of stack_traceLiming Wang
Impact: make output of stack_trace complete if buffer overruns When read buffer overruns, the output of stack_trace isn't complete. When printing records with seq_printf in t_show, if the read buffer has overruned by the current record, then this record won't be printed to user space through read buffer, it will just be dropped in this printing. When next printing, t_start should return the "*pos"th record, which is the one dropped by previous printing, but it just returns (m->private + *pos)th record. Here we use a more sane method to implement seq_operations which can be found in kernel code. Thus we needn't initialize m->private. About testing, it's not easy to overrun read buffer, but we can use seq_printf to print more padding bytes in t_show, then it's easy to check whether or not records are lost. This commit has been tested on both condition of overrun and non overrun.

2008-11-20[IA64] Rationalize kernel mode alignment checkingTony Luck
Itanium processors can handle some misaligned data accesses. They also provide a mode where all such accesses are forced to trap. The kernel was schizophrenic about use of this mode: * Base kernel code ran in permissive mode where the only traps generated were from those cases that the h/w could not handle. * Interrupt, syscall and trap code ran in strict mode where all unaligned accesses caused traps to the 0x5a00 unaligned reference vector. Use strict alignment checking throughout the kernel, but make sure that we continue to let user mode use more relaxed mode as the default. Signed-off-by: Tony Luck <tony.luck@intel.com>
2008-11-20x86: Fix interrupt leak due to migrationMatthew Wilcox
When we migrate an interrupt from one CPU to another, we set the move_in_progress flag and clean up the vectors later once they're not being used. If you're unlucky and call destroy_irq() before the vectors become un-used, the move_in_progress flag is never cleared, which causes the interrupt to become unusable. This was discovered by Jesse Brandeburg for whom it manifested as an MSI-X device refusing to use MSI-X mode when the driver was unloaded and reloaded repeatedly.

2008-11-20SUNRPC: Fix a performance regression in the RPC authentication codeTrond Myklebust
Fix a regression reported by Max Kellermann whereby kernel profiling showed that his clients were spending 45% of their time in rpcauth_lookup_credcache. It turns out that although his processes had identical uid/gid/groups, generic_match() was failing to detect this, because the task->group_info pointers were not shared. This again lead to the creation of a huge number of identical credentials at the RPC layer. The regression is fixed by comparing the contents of task->group_info if the actual pointers are not identical.

But since translate_usr_offset() returns -1 for invalid offsets, addr can now get the value 0xffffffff which then fails the next return-value sanity check and thus the kernel tries to access invalid memory: if (addr < 0) break; Fix this bug by modifying translate_usr_offset() to take and return values of type compat_ulong_t, and by returning the value "sizeof(struct pt_regs)" as an error indicator. Additionally change the sanity check to check for return values for >= sizeof(struct pt_regs). This patch survived my compile and run-tests.

2008-11-20[CIFS] Do not attempt to close invalidated file handlesSteve French
If a connection with open file handles has gone down and come back up and reconnected without reopening the file handle yet, do not attempt to send an SMB close request for this handle in cifs_close. We were checking for the connection being invalid in cifs_close but since the connection may have been reconnected we also need to check whether the file handle was marked invalid (otherwise we could close the wrong file handle by accident).

2008-11-20asix: Fix asix-based cards connecting to 10/100Mbs LAN.Pantelis Koukousoulas
Add AX_MEDIUM_ENCK also when speed = 10/100Mbps. This allows my belkin f5d5055 to work with my 100Mbps switch and with an old 10Mbps ISA card. Without this patch, the card is recognized and the interface is brought up fine, but no packets actually flow through the interface.

2008-11-20mv643xx_eth: fix recycle check boundLennert Buytenhek
When mv643xx_eth allocates skbuffs, it adds 'dma_get_cache_alignment() - 1' to the length it needs, so that it can align the skb's ->data pointer to a cache boundary. When checking whether a transmitted skbuff can be reused as a receive buffer, these bytes needs to be included into the minimum bound for the recycle check.

2008-11-20TPROXY: supply a struct flowi->flags argument in inet_sk_rebuild_header()Balazs Scheidler
inet_sk_rebuild_header() does a new route lookup if the dst_entry associated with a socket becomes stale. However inet_sk_rebuild_header() didn't use struct flowi->flags, causing the route lookup to fail for foreign-bound IP_TRANSPARENT sockets, causing an error state to be set for the sockets in question.

2008-11-20TPROXY: fill struct flowi->flags in udp_sendmsg()Balazs Scheidler
udp_sendmsg() didn't fill struct flowi->flags, which means that the route lookup would fail for non-local IPs even if the IP_TRANSPARENT sockopt was set. This prevents sendto() to work properly for UDP sockets, whereas bind(foreign-ip) + connect() + send() worked fine. Signed-off-by: Balazs Scheidler <bazsi@balabit.hu> Signed-off-by: David S.

2008-11-19USB: usbmon: fix read(2)Pete Zaitcev
There's a bug in the usbmon binary reader: When using read() to fetch the packets and a packet's data is partially read, the next read call will once again return up to len_cap bytes of data. The b_read counter is not regarded when determining the remaining chunk size. So, when dumping USB data with "cat /dev/usbmon0 > usbmon.trace" while reading from a USB storage device and analyzing the dump file afterwards it will get out of sync after a couple of packets.

2008-11-19USB: gadget rndis: send notificationsRichard Röjfors
It turns out that atomic_inc_return() returns the *new* value not the original one, so the logic in rndis_response_available() kept the first RNDIS response notification from getting out. This prevented interoperation with MS-Windows (but not Linux). Fix this to make RNDIS behave again.

2008-11-19USB: gadget rndis: stop windows self-immolationDavid Brownell
Somewhere in the conversion of the RNDIS gadget code to the new framework, the descriptor of its data interface seems to have been copied from the CDC Ethernet driver. Unfortunately that means it got a nonzero altsetting ... which is incorrect. Issue uncovered by Richard Röjfors <richard.rojfors@endian.se>. This patch fixes that problem, and resolves at least some cases of Windows XP bluescreening itself. Tested-by: Richard Röjfors <richard.rojfors@endian.se>.
