Bug#991286: unblock: netdiscover/0.7-4
Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock
X-Debbugs-Cc: eriberto@debian.org
Dear Release Team,
Please unblock package netdiscover.
[ Reason ]
The revision 0.7-4 has a patch (030) to add an important fix from the
upstream[1]. This fix allows netdiscover to use correctly CIDR /24 if
netdiscover is being built with libpcap >= 1.10.
This fix closes #991258
[1] https://github.com/netdiscover-scanner/netdiscover/commit/2de0187c8b6aad3ca5393d96fbc5b00c453c3d23
Short explanation: Older versions of libpcap ignored to_ms on Linux. The
current version captures packets until a buffer a filled or the specified
timeout elapses. The value 0 disables that timeout, so libpcap will only start
delivering packets once the buffer is filled.
[ Impact ]
If the unblock isn't granted, the user will not able to scan a network using
the option '-r <IP>/24', so only /8 and /16 will work.
[ Tests ]
Several tests were made after the fix and it worked fine.
[ Risks ]
This is a trivial fix and it has no risks for the whole source code.
[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing
