* mdoc(7) police: s/BSD/.Bx/ where appropriate.Ruslan Ermilov2001-08-141-3/+6

* output_data(), output_datalen() and netflush() didn't actually guaranteeKris Kennaway2001-07-236-45/+50
| | | | | | | | | | | | | | | | to do what they are supposed to: under some circumstances output data would be truncated, or the buffer would not actually be flushed (possibly leading to overflows when the caller assumes the operation succeeded). Change the semantics so that these functions ensure they complete the operation before returning. Comment out diagnostic code enabled by '-D reports' which causes an infinite recursion and an eventual crash. Patch developed with assistance from ru and assar. Notes: svn path=/head/; revision=80224
* More potential buffer overflow fixes.Ruslan Ermilov2001-07-204-35/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Fixed `nfrontp' calculations in output_data(). If `remaining' is initially zero, it was possible for `nfrontp' to be decremented. Noticed by: dillon o Replaced leaking writenet() with output_datalen(): : * writenet : * : * Just a handy little function to write a bit of raw data to the net. : * It will force a transmit of the buffer if necessary : * : * arguments : * ptr - A pointer to a character string to write : * len - How many bytes to write : */ : void : writenet(ptr, len) : register unsigned char *ptr; : register int len; : { : /* flush buffer if no room for new data) */ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : if ((&netobuf[BUFSIZ] - nfrontp) < len) { : /* if this fails, don't worry, buffer is a little big */ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : netflush(); : } : : memmove(nfrontp, ptr, len); : nfrontp += len; : : } /* end of writenet */ What an irony! :-) o Optimized output_datalen() a bit.
