Subject: [PATCH v3 0/3] handle sysconf(_SC_PAGESIZE) negative return value
Date: Tue, 24 Jun 2025 08:03:30 +0000	[thread overview]
Message-ID: <20250624080333.127618-1-mb@smartsharesystems.com> (raw)
In-Reply-To: <20250610131348.248800-1-mb@smartsharesystems.com>

Coverity reports some defects, where the root cause seems to be negative
return value from sysconf(_SC_PAGESIZE) not being handled.
This series addresses those defects in the DPDK libraries.

PS: "_SC_PAGESIZE" has the alias "_SC_PAGE_SIZE". Both are covered here.

Morten Brørup (3):
  eal/unix: fix log message for madvise() failure
  eal: handle sysconf(_SC_PAGESIZE) negative return value
  pmu: handle sysconf(_SC_PAGESIZE) negative return value
