* Prevent fd exhaustion in the parent when loading the listening serverreyk2016-10-121-6/+25
| | | | | | | | sockets by sending the fd one-by-one. This allows to start httpd with max 32 server instances and many server sockets without changing the default rlimits in any way. OK rzalamena@
* Modify httpd(8)'s proc.c to use less file descriptors during the daemonrzalamena2016-10-101-66/+73
| | | | | | | | | | start up. To achieve this proc_init() initiates only the necessary pipes between child and parent, allocate and distribute fds in proc_connect(). In case of configuration checks ('-n') we do nothing in proc_init() and proc_connect(). ok reyk@

* Kill p_instance from proc.c and remove static proc_id unused variables.rzalamena2016-08-271-7/+6
| | | | | | | | | To keep the debug functionality intact and correct we'll use the pid field in the imsg header to pass the instance number. Remember to always pass 'ps_instance + 1' otherwise libutil will fill imsg header pid field with the imsgbuf pid (which is the current process pid). ok reyk@
* Kill the ps_ninstances from proc.c.rzalamena2016-08-261-10/+12
| | | | | | | We got the same information in ps_instances[proc] (more accurate) and we avoid allocating unnecessary memory for pipe storage. ok reyk@

* Change httpd(8) to use C99-style fixed-width integers (uintN_t insteadreyk2015-08-201-18/+19
| | | | | | | | | | | | | | | | of u_intN_t) and replace u_int with unsigned int. Mixing both variants is a bad style and most contributors seem to prefer this style; it also helps us to get used to it, portability, and standardization. Theoretically no binary change, except one in practice: httpd.o has a different checksum because gcc with -O2 pads/optimizes "struct privsep" differently when using "unsigned int" instead "u_int" for the affected members. "u_int" is just a typedef of "unsigned int", -O0 doesn't build the difference and clang with -O2 doesn't do it either - it is just another curiosity from gcc-land. OK semarie@
* httpd is based on relayd and had included many headers that are onlyreyk2015-01-211-6/+2
| | | | | | | | | needed by its ancestor. jsg@, include-what-you-use, and some manual review helped to cleanup the headers (take iwyu with a grain of salt). Based on common practice, httpd.h now also includes the necessary headers for itself. OK florian@

web server. It is not finished yet and I just started it today, but the goal is to provide an HTTP server that a) provides minimal features, b) serves static files, c) provides FastCGI support, and d) follows common coding practices of OpenBSD. It will neither support plugins, nor custom memory allocators, EBCDIC support, PCRE or any other things that can be found elsewhere. httpd(8) is not intended to provide a fully-featured replacement for nginx(8) or the Apache, but it will provide enough functionality that is needed in the OpenBSD base system. ok deraadt@
