ibacm: Incorrect list used for subnet list causes a segfault
|
|
|
|
Setting the provider keyword in the ibacm_opts.cfg file to something
|
|
other than 'default' will cause ibacm to segfault on startup:
|
|
|
|
ibacm[32739]: segfault at 302e40 ip 000000000040432d
|
|
sp 00007ffe4039e1c0 error 4 in ibacm[400000+c000]
|
|
|
|
To re-produce the segfault, change the provider keyword in
|
|
ibacm_opts.cfg from:
|
|
|
|
provider ibacmp default
|
|
|
|
to:
|
|
|
|
provider ibacmp 0xFE80000000000000
|
|
|
|
When adding subnets to a provider subnet list, the incorrect list is
|
|
used. The list used is the provider_list (list of all providers)
|
|
rather than the (specific) provider subnet list.
|
|
|
|
This corrupts the provider_list, and causes ibacm to crash with the
|
|
above segfault.
|
|
|
|
Use the correct list when adding subnet information to a provider.
|
|
