[infiniband] Return status code from ib_create_cq() and ib_create_qp()

2017-03-22T09:18:02+00:00

Any underlying errors arising during ib_create_cq() or ib_create_qp() are lost since the functions simply return NULL on error. This makes debugging harder, since a debug-enabled build is required to discover the root cause of the error. Fix by returning a status code from these functions, thereby allowing any underlying errors to be propagated. Signed-off-by: Michael Brown

[ipoib] Fix a race when chain-loading undionly.kpxe in IPoIB

2015-08-17T13:42:36+00:00

The Infiniband link status change callback ipoib_link_state_changed() may be called while the IPoIB device is closed, in which case there will not be an IPoIB queue pair to be joined to the IPv4 broadcast group. This leads to NULL pointer dereferences in ib_mcast_attach() and ib_mcast_detach(). Fix by not attempting to join (or leave) the broadcast group unless we actually have an IPoIB queue pair.

[build] Fix the REQUIRE_SYMBOL mechanism

2015-03-05T00:59:38+00:00

At some point in the past few years, binutils became more aggressive at removing unused symbols. To function as a symbol requirement, a relocation record must now be in a section marked with @progbits and must not be in a section which gets discarded during the link (either via --gc-sections or via /DISCARD/). Update REQUIRE_SYMBOL() to generate relocation records meeting these criteria. To minimise the impact upon the final binary size, we use existing symbols (specified via the REQUIRING_SYMBOL() macro) as the relocation targets where possible. We use R_386_NONE or R_X86_64_NONE relocation types to prevent any actual unwanted relocation taking place. Where no suitable symbol exists for REQUIRING_SYMBOL() (such as in config.c), the macro PROVIDE_REQUIRING_SYMBOL() can be used to generate a one-byte-long symbol to act as the relocation target. If there are versions of binutils for which this approach fails, then the fallback will probably involve killing off REQUEST_SYMBOL(), redefining REQUIRE_SYMBOL() to use the current definition of REQUEST_SYMBOL(), and postprocessing the linked ELF file with something along the lines of "nm -u | wc -l" to check that there are no undefined symbols remaining.
