dasd: correct device table

2011-04-28T15:21:13+00:00

commit 5da24b7627ff821e154a3aaecd5d60e1d8e228a5 upstream. The 3880 storage control unit supports a 3380 device type, but not a 3390 device type.

keyboard: integer underflow bug

2011-03-31T18:58:19+00:00

commit b652277b09d3d030cb074cc6a98ba80b34244c03 upstream. The "ct" variable should be an unsigned int. Both struct kbdiacrs ->kb_cnt and struct kbd_data ->accent_table_size are unsigned ints. Making it signed causes a problem in KBDIACRUC because the user could set the signed bit and cause a buffer overflow.

[SCSI] zfcp: Update status read mempool

2010-07-21T22:05:09+00:00

Commit 64deb6efdc5504ce97b5c1c6f281fffbc150bd93 changed the way status read buffers are handled but forgot to adjust the mempool to the new size. Add the call to resize the mempool after the exchange config data. Also use the define instead of the hard coded number in the fsf callback for consistency.

[SCSI] zfcp: Do not wait for SBALs on stopped queue

2010-07-21T22:05:07+00:00

Trying to read the FC host statistics on an offline adapter results in a 5 seconds wait. Reading the statistics tries to issue an exchange port data request which first waits up to 5 seconds for an entry in the request queue. Change the strategy for getting a free SBAL to exit when the queue is stopped. Reading the statistics will then fail without the wait.

[SCSI] zfcp: Fix check whether unchained ct_els is possible

[S390] cio: fix potential overflow in chpid descriptor

2010-07-19T07:22:50+00:00

The length filed in the chsc response block (if valid) has a value of n*(sizeof(chp_desc))+8 (for the response block header). When we memcopied from the response block to the actual descriptor we copied 8 bytes too much. The bug was not revealed since the descriptor is embedded in struct channel_path. Since we only write one descriptor at a time ignore the length value and use sizeof(*desc). Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky
