[lwip-devel] [bug #57375] Assertion "mss_local is too small" failed

[Erik Ekman]

Follow-up Comment #1, bug #57375 (project lwip):

I can reproduce this with the latest code by simulating the old rand
implementation:

$ cd test/fuzz
$ make all D="-DLWIP_RAND_FOR_FUZZ_SIMULATE_GLIBC"
$ ./lwip_fuzz3 crashed_inputs/004
reading input from file... testing file: "crashed_inputs/004"...
Assertion "mss_local is too small" failed at line 486 in
../../src/core/tcp_out.c
Aborted (core dumped)


The relevant code was changed in fixing bug #25882, bug #36153 and bug #37184,
so any fix must be carefully designed.
