* Adjust for kern.ps_strings and PS_STRINGS not being a pointer. ThisBruce Evans1998-12-161-17/+12
| | | | | | | | | | | | | fixes a type mismatch in the call to kvm_uread(). The bug has gone undetected for almost 3 years because kvm_uproc()'s protoype has been disabled for almost 4 years. Trust sysctlbyname() to work properly if it succeeds. Fixed style bugs in revs. 1.19 and 1.22. Notes: svn path=/head/; revision=41880

* Probable fix for the "cdda2wav" panics that various people have beenKenneth D. Merry1998-12-161-47/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | reporting since this past summer. (I think Daniel O'Conner was the first.) The problem appears to have been something like this: - cdda2wav by default passes in a buffer that is close to the 128K MAXPHYS limit. - many times, the buffer is not page aligned - vmapbuf() truncates the address, so that it is page aligned - that causes the total size of the buffer to be greater than MAXPHYS, which of course is a bad thing. Here's a quote from the PR (kern/9067): ================== In particular, note bp->b_bufsize = 0x0001f950 and bp->b_data = 0xf2219960 (which does not start on a page boundary). vunmapbuf() loops through all the pages without any difficulty until addr reaches 0xf2239000, and then the panic occurs. This seems to indicate that we are exceeding MAXPHYS since we actually started from the middle of a page (the data is being transfered to a non page aligned location). To complete the description, note that the system call originates from ReadCddaMMC12() (in scsi_cmds.c of cdda2wav) with a request to read 55 audio sectors of 2352 bytes (which is calculated to fall under MAXPHYS). This in turn ends up calling scsi_send() (in scsi-bsd.c) which calls cam_fill_csio() and cam_send_ccb(). This results in a CAMIOCOMMAND ioctl with a ccb function code of XPT_SCSI_IO. ================== The fix is to change the size check in cam_periph_mapmem() so that it is like the one in minphys(). In particular, it is something like: if ((buffer_length + (buf_ptr & PAGE_MASK)) > MAXPHYS) buffer is too big My fix is based on the one in the PR, but I cleaned up a fair number of things in cam_periph_mapmem(). The checks for each buffer to be mapped are now in a separate loop from the actual mapping operation. With the new arrangement, we don't have to bother with unmapping any previously mapped buffers if one of the checks fails. Many thanks to James Liu for tracking this down. I'd appreciate it if some vm-savvy folks would look this over. I believe this fix is correct, but I could be wrong. PR: kern/9067 (also, kern/8112) Reviewed by: gibbs Submitted by: "James T.

| | | | | | | | | | adjusted related casts to match (only in the kernel in this commit). The pointer was only wanted in one place in kern_exec.c. Applications should use the kern.ps_strings sysctl instead of PS_STRINGS, so they shouldn't notice this change. Notes: svn path=/head/; revision=41871

| | | | | | | | | | | | | | | | | | | on rshd and rlogind. However, note that: 1: rshd used to drop a connection with -a if the hostname != ip address. This is unneeded, because iruserok() does it's own checking. It was also wrong if .rhosts had an explicit IP address in it, connections would be dropped from that host solely because the DNS was mismatched even though it was explicitly intended to work by IP address. 2: rlogind and rshd check the hostname mappings by default now because that is what goes into the utmp/wtmp and logs. If the hostname != ip address, then it uses the IP address for logging/utmp/wtmp purposes. There isn't much point logging ficticious hostnames. 3: rshd -a is now accepted (but ignored) for compatability. If you really want to make life miserable for people with bad reverse DNS, use tcpd in paranoid mode (which is questionable anyway, given DNS ttl tweaking). Notes: svn path=/head/; revision=41860
