* treewide: Kill assignments in if conditions.Ralf Baechle2017-07-311-1/+2
| | | | | | | | | | | | | | | | | | | | Somewhat hard to read and the code base already has many overlong lines. Found with below spatch file and some manual editing in ax25/access.c to restore a comment lost by spatch. @parens@ expression E, F, G; binary operator X; statement S; @@ - if ((E = F) X G) + E = F; + if (E X G) S Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* axwrapper: Compute nfds argument of select() instead of using a constant.Ralf Baechle2017-07-261-1/+10
| | | | | | | In particular this remove reliance on how file descriptors are assigned and ensures we don't pass an unnecessarily high nfds argument to select. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

No point in keeping this around; SIGCHLD is perfectly fine. Fixes: 71918b7d4e95 ("axwrapper: Mark functions sigchld_handler and convert_{cr_lf,lf_cr} static.")

* axwrapper: Mark functions sigchld_handler and convert_{cr_lf,lf_cr} static.Ralf Baechle2017-02-061-3/+3
| | | | | | | | This results in a new warning about sigchld_handler() being unused which is because the caller is currently commented out which we leave to be sorted out later. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Axwrapper first creates a pipe and then forks and execs the program <server-program> with arguments given at the axwrapper command line. The argv[0] argument is mandatory; further arguments are optional. The parent process then sits and waits for any I/O to and from the user and converts any carriage return characters from the user to line feeds and any line feeds from the program to carriage returns. This is useful when starting non-AX.25-aware programs from ax25d. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
