2007-08-11fix serial buffer memory leakAlan Cox1-6/+50
Patch c5c34d4862e18ef07c1276d233507f540fb5a532 (tty: flush flip buffer on ldisc input queue flush) introduces a race condition which can lead to memory leaks. The problem can be triggered when tcflush() is called when data are being pushed to the line discipline driver by flush_to_ldisc(). flush_to_ldisc() releases tty->buf.lock when calling the line discipline receive_buf function. At that poing tty_buffer_flush() kicks in and sets both tty->buf.head and tty->buf.tail to NULL. When flush_to_ldisc() finishes, it restores tty->buf.head but doesn't touch tty->buf.tail. This corrups the buffer queue, and the next call to tty_buffer_request_room() will allocate a new buffer and overwrite tty->buf.head. The previous buffer is then lost forever without being released. (Thanks to Laurent for the above text, for finding, disgnosing and reporting the bug) - Use tty->flags bits for the flush status. - Wait for the flag to clear again before returning - Fix the doc error noted - Fix flush of empty queue leaving stale flushpending [akpm@linux-foundation.org: cleanup] Signed-off-by: Alan Cox <alan@redhat.com> Acked-by: Paul Fulghum <paulkf@microgate.com> Cc: Laurent Pinchart <laurentp@cse-semaphore.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-07-31ipmi: Fix mem leak in try_init_dmi()Jesper Juhl1-0/+1
This is only called at init time and only happens if the BIOS screws something up, so the leak is slight and it is probably not worth sending to 2.6.22.x. The driver would not initialize the interface in the case, and I have no reports of this happening. I have booted and run tests on a system with this patch. Note that the original patch was munged by the mailer, here's a new one. If we ever hit the "default:" case in the switch in try_init_dmi(), then we'll leak the storage allocated with kzalloc() and assigned to 'info'.

Remove fs.h from mm.h. For this, 1) Uninline vma_wants_writenotify(). It's pretty huge anyway. 2) Add back fs.h or less bloated headers (err.h) to files that need it.

2007-07-29[WATCHDOG] Fix pcwd_init_module crashWim Van Sebroeck1-1/+0
Fix for the problem detected by Ingo Molnar: enabling CONFIG_PCWATCHDOG=y crashes bzImage bootup. The reason for this can be found in drivers/makefile We first do: obj-y += char/ and later we do: obj-y += base/ block/ misc/ mfd/ net/ media/ So if we put a platform or isa or usb bus driver in char/watchdog (which is called from the Makefile in drivers/char/Makefile) then we didn't have the different device drivers initialized yet (they are in drivers/base and drivers/usb and ...) This fix makes sure that we compile the watchdog drivers after drivers/base, drivers/misc, drivers/pci and drivers/usb. We also do the compile after hwmon because in the future the watchdog temperature support will use the hwmon system. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2007-07-27Fix "use after free" / "double free" bug in ati_create_gatt_pages / ati_free_gatt_pagesJesper Juhl1-7/+2
Hi, Coverity spotted a "use after free" bug in drivers/char/agp/ati-agp.c::ati_create_gatt_pages(). The same one that was in drivers/char/agp/amd-k7-agp.c::amd_create_gatt_pages() The problem is this: If "entry = kzalloc(sizeof(struct ati_page_map), GFP_KERNEL);" fails, then there's a loop in the function to free all entries allocated so far and break out of the allocation loop. That in itself is pretty sane, but then the (now freed) 'tables' is assigned to ati_generic_private.gatt_pages and 'retval' is set to -ENOMEM which causes ati_free_gatt_pages(); to be called at the end of the function. The problem with this is that ati_free_gatt_pages() will then loop 'ati_generic_private.num_tables' times and try to free each entry in tables[] - this is bad since tables has already been freed and furthermore it will call kfree(tables) at the end - a double free. This patch removes the freeing loop in ati_create_gatt_pages() and instead relies entirely on the call to ati_free_gatt_pages() to free everything we allocated in case of an error. It also sets ati_generic_private.num_tables to the actual number of entries allocated instead of just using the value passed in from the caller - this ensures that ati_free_gatt_pages() will only attempt to free stuff that was actually allocated. Note: I'm in no way intimate with this code and I have no way to actually test this patch (besides compile test it), so while I've tried to be careful in reading the code and make sure the patch does the right thing an ACK from someone who actually knows the code in-depth would be very much appreciated.
