| | | | | | | | | | aren't silently converted to minbrk. This stops malloc(INT_MAX) from dumping core. Small values are still silently converted. They should be an error. sbrk() doesn't do any range checking or conversions or overflow checking. Moved PIC_EPILOGUE invocation to a more natural place where it obviously doesn't interfere with the comparison.

| | | | | | | | | Document the fact that the tracefile argument must lead to a regular file. Also took the opportunity to remove the spurious "Errors" entry relating to filenames with the high-order bit set and add $Id$. (More of the same to follow if there are no objections).
* Suggested by: Bruce Evans, Jeffrey Hsu, Gary Palmerjraynard1996-06-2257-50/+317
| | | | | | | | | | | | | | | | | | | | | Added $Id$'s to files that were lacking them (gpalmer), made some cosmetic changes to conform to style guidelines (bde) and checked against NetBSD and Lite2 to remove unnecessary divergences (hsu, bde) One last code cleanup:- Removed spurious casts in fseek.c and stdio.c. Added missing function argument in fwalk.c. Added missing header include in flags.c and rget.c. Put in casts where int's were being passed as size_t's. Put in missing prototypes for static functions. Changed second args of __sflags() inflags.c and writehook() in vasprintf.c from char * to const char * to conform to prototypes. This directory now compiles with no warnings with -Wall under gcc-2.6.3 and with considerably less warnings than before with the ultra-pedantic script I used for testing. (Most of the remaining ones are due to const poisoning).

* Make _yp_dobind() a litle smarter:wpaul1996-06-011-2/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we preserve RPC handles instead of rebuilding them each time a ypcln function is called, we have to be careful about keeping our sockets in a sane state. It's possible that the caller may call a ypclnt function, and then decide to close all its file descriptors. This would also close the socket descriptor held by the yplib code. Worse, it could re-open the same descriptor number for its own use. If it then calls another ypclnt function, the subsequent RPC will fail because the socket will either be gone or replaced with Something Completely Different. The yplib code will recover by rebinding, but it doing so it may wreck the descriptor which now belongs to the caller. To fix this, _yp_dobind() needs to label the descriptor somehow so that it can test it later to make sure it hasn't been altered between ypclnt calls. It does this by binding the socket, thus associating a port number with it. It then saves this port number in the dom_local_port member of the dom_binding structure for the given domain. When _yp_dobind() is called again (which it is at the start of each ypclnt function), it checks to see if the domain is already bound, and if it is, it does a getsockname() on the socket and compares the port number to the one it saved. If the getsockname() fails, or the port number doesn't match, it abandons the socket and sets up a new client handle. This still incurs some syscall overhead, which is what I was trying to avoid, but it's still not as bad as before.
* Improve NIS performace of getservbyname() and getservbyport(). Both thesewpaul1996-06-013-7/+123
| | | | | | | | | | | | | | | | | | | | | | functions are implimented as wrappers around getservent(), which means it's up to getservent() to do all the work. The NIS support in getservent() only allows it to scan through the services.byname map one entry at a time until it finds the requested service name/port. This can be painfully slow due to the overhead involved (lots and lots of successive RPCs). To fix this, we allow getservbyname() and getservbyport() to signal getservent() that if NIS is turned on (there's a '+' in /etc/services), the usual yp_first()/yp_next() linear search should be abandoned and yp_match() used instead. This causes getservent() to immediately locate the requested entry instead of wasting time groping through the whole map. The downside is that this trick is accomplished by exporting a couple of pointers from getservent.c which getservbyname.c and getservbyport.c can preset in order to tell getservent() what to do. If all three functions were in the same source module, then the extra cruft could be delcared static to avoid poluting the global symbol space. Maybe they should be combined anyway. For now I've settled on prepending lots of underscores.

| | | | | | | | | privileged port within a single bind(), rather than looping through attempts to bind over and over again over progressively lower ports. This should speed up rlogin/rsh etc, and will probably cure some of the strange rlogin hangs that have been reported in the past where rresvport() managed to bind() to a port address that it shouldn't have.

| | | | | | | | | | | | | | | | | | | | | | | | | | not based on gpl'ed code, just prototype and usage. I'm not 100% certain they behave the same while the system is in trouble (eg: malloc() failing) but in those circumstances all bets would be off anyway. These routines work like sprintf() and vsprintf(), except that instead of using a fixed buffer, they allocate memory and return it to the user and it's the user's responsibility to free() it. They have allocate as much memory as they need (and can get), so the size of strings it can deal with is limited only by the amount of memory it can malloc() on your behalf. There are a few gpl'ed programs starting to use this interface, and it's becoming more common with the scares about security risks with sprintf(). I dont like the look of the code that the various programs (including cvs, gdb, libg++, etc) provide if configure can't find it on the system. It should be possible to modify the stdio core code to provide this interface more efficiently, I was more worried about having something that worked and was secure. :-) (I noticed that there was once intended to be a smprintf() routine when our stdio was written for 4.4BSD, but it looks pretty stillborn, and it's intended interface is not clear). Since Linux and gnu libc have this interface, it seemed silly to bring yet another one onto the scene.
