[dm-devel] [PATCH v2 0/4] [PATCH 0/4] libmpathpersist allocation size fixes

[mwilck at suse.com]

From: Martin Wilck <mwilck at suse.com>

Hi Christophe,

We recently found a problem with mpathpersist using an allocation length
of > 8192 bytes for PERSISTENT RESERVE IN/OUT commands. This patch set
tries to fix it. The last patch would change the ABI for external programs,
it's optional.

(Christophe, to avoid misunderstanding:	This set is not meant to be included
in the upcoming merge).

Reviews and comments welcome.

Changes in v2:
 - 02/04: fix overflow calculation (Ben)
 - 04/04: improve commit description wrt ABI breakage

Martin Wilck (4):
  libmpathpersist: limit PRIN allocation length to 8192 bytes
  libmpathpersist: format_transportids(): avoid PROUT overflow
  libmpathpersist: mpath_format_readfullstatus(): use real buffer size
  libmpathpersist: ABI change: limit data-in/out size to 8192 bytes
