Subject: [PATCH v2 0/3] Improved exit()/_exit() handling
Date: Thu, 11 Dec 2025 14:54:33 +1100	[thread overview]
Message-ID: <20251211035436.2844623-1-david@gibson.dropbear.id.au> (raw)

As discussed on IRC, while working on the forwarding extensions, I
discovered that failures at certain points of initialisation (in
particular tcp_init() or udp_init() can result in a zombie pasta child
process.

Here's a fix.

v2:
 * Fix a typo
 * Use PR_SET_PDEATHSIG instead of explicit kill()
 * Include updated version of Laurent's cppcheck bug workaround

David Gibson (2):
  treewide: Introduce passt_exit() helper
  pasta: Clean up waiting pasta child on failures

Laurent Vivier (1):
  tcp: Suppress new instance of cppcheck bug 14191
