atm: firestream: check the return value of ioremap() in fs_init()

2022-03-23T08:01:34+00:00

[ Upstream commit d4e26aaea7f82ba884dcb4acfe689406bc092dc3 ] The function ioremap() in fs_init() can fail, so its return value should be checked. Reported-by: TOTE Robot Signed-off-by: Jia-Ju Bai Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

firestream: Fix memleak in fs_open

[ Upstream commit 15ac5cdafb9202424206dc5bd376437a358963f9 ] When make_rate() fails, vcc should be freed just like other error paths in fs_open(). Signed-off-by: Dinghao Liu Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

firestream: fix memory leaks

2020-01-29T14:02:35+00:00

[ Upstream commit fa865ba183d61c1ec8cbcab8573159c3b72b89a4 ] In fs_open(), 'vcc' is allocated through kmalloc() and assigned to 'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g., there is no more free channel, an error code EBUSY or ENOMEM will be returned. However, 'vcc' is not deallocated, leading to memory leaks. Note that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated in fs_close(). But, if fs_open() fails, there is no guarantee that fs_close() will be invoked. To fix this issue, deallocate 'vcc' before the error code is returned. Signed-off-by: Wenwen Wang Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

atm: firestream: constify pci_device_id.

2017-07-16T23:38:02+00:00

pci_device_id are not supposed to change at runtime. All functions working with pci_device_id provided by work with const pci_device_id. So mark the non-const structs as const.

lib/vsprintf.c: remove %Z support

2017-02-28T02:43:47+00:00

Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

Replace with globally

2016-12-24T19:46:01+00:00

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

atm: firestream: add more reserved strings

2016-05-31T18:52:59+00:00

This bug was there when the driver was first added in back in year 2000. It causes a Smatch warning: drivers/atm/firestream.c:849 process_incoming() error: buffer overflow 'res_strings' 60 <= 63 There are supposed to be 64 entries in this array and the missing strings are clearly in the 30 40 range. I added them as reserved 37 to reserved 40. It's possible that strings are really supposed to be added in the middle instead of at the end, but this approach is safe, in that it fixes the bug and doesn't break anything that wasn't already broken.

atm: firestream: Use del_timer_sync() in teardown path

2014-03-26T01:06:02+00:00

The device is about to vanish. So we need to make sure that the timer is completely stopped and the callback is not running on another CPU. Signed-off-by: Thomas Gleixner Cc: Chas Williams Cc: atm Cc: netdev Signed-off-by: David S. Miller

atm: firestream: fix interruptible_sleep_on race

2014-02-26T21:06:12+00:00

interruptible_sleep_on is racy and going away. This replaces the one use in the firestream driver with the appropriate wait_event_interruptible variant.
