* listen: Fix potential buffer overflow.Ralf Baechle2021-07-281-3/+3
| | | | | | | | | | | | | | | | | | | | Sounds evil but would only be exploitable when getservbyport is accessing a database that's under an attacker's control. The /etc/services file shipping with Fedora 34 has entries of a maximum length of 15 characters so are just fine. Fixed by not copying the string returned by getservbyport - which also is faster. At that point it becomes possible to reduce the length of str[] to 6 bytes. Found by the following GCC 11 warning: gcc -DHAVE_CONFIG_H -I. -I.. -g -O2 -Wall -MT utils.o -MD -MP -MF .deps/utils.Tpo -c -o utils.o utils.c utils.c: In function ‘servname’: utils.c:124:17: warning: ‘strncpy’ specified bound 16 equals destination size [-Wstringop-truncation] 124 | strncpy(str, serv->s_name, 16); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* listen: Fix overzealous GCC warnings.Ralf Baechle2021-07-281-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 11 has returned to the old tradition of overzealous warnings.

Reason: the defragmented packet is passed to netif_rx(skb). It has skb->protocol = htons(ETH_P_IP), but still belongs to ifr.ifr_hwaddr.sa_family == AF_AX25. listen -a looks for every iface with like ifr.ifr_hwaddr.sa_family == AF_AX25 and thus gets the desegmented packet.

* Remove all generated files.Ralf Baechle2009-06-191-539/+0
| | | | | | | | | | | | | | Keeping generated files in CVS doesn't only tend to produce large and cluttered files it also may result in build problems due to timestamps in the wrong order. So dump everything, update .cvsignore to ignore these files and resolve all warnings generated by autoreconf. From now on users of a CVS checkout should run the command autoreconf --install --force after having done a CVS checkout. For this to succeed automake, autoconf and libtool will have to be installed.
* Fix type of length argument to sockset syscalls.Ralf Baechle2009-06-141-1/+1
| | | | | | | | Various socket syscalls receive a length argument that should be a socklen_t rsp. a ptr to a socklen_t but instead int rsp. ptr to int were being passed. While in theory this was a bug it's harmless as dangerously large values would not be used but the issue manifested itself in a significant number of compilation warnings.
