* Change the default disposition of debug.mpsafenet from 0 to 1, whichRobert Watson2004-08-283-3/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | will cause the network stack to operate without the Giant lock by default. This change has the potential to improve performance by increasing parallelism and decreasing latency in network processing. Due to the potential exposure of existing or new bugs, the following compatibility functionality is maintained: - It is still possible to disable Giant-free operation by setting debug.mpsafenet to 0 in loader.conf. - Add "options NET_WITH_GIANT", which will restore the default value of debug.mpsafenet to 0, and is intended for use on systems compiled with known unsafe components, or where a more conservative configuration is desired. - Add a new declaration, NET_NEEDS_GIANT("componentname"), which permits kernel components to declare dependence on Giant over the network stack. If the declaration is made by a preloaded module or a compiled in component, the disposition of debug.mpsafenet will be set to 0 and a warning concerning performance degraded operation printed to the console. If it is declared by a loadable kernel module after boot, a warning is displayed but the disposition cannot be changed. This is implemented by defining a new SYSINIT() value, SI_SUB_SETTINGS, which is intended for the processing of configuration choices after tunables are read in and the console is available to generate errors, but before much else gets going. This compatibility behavior will go away when we've finished the last of the locking work and are confident that operation is correct. Notes: svn path=/head/; revision=134443

* Also, match the full path to the special nologin shell.Mike Makonnen2004-08-281-1/+2
| | | | | | | | | | | | | Previously, it would recognize it as a valid shell only if the basename (nologin) was specified. Now, it will recognize both the basename and the full path. NOTE: The full path as adduser(8) understands it is /usr/sbin/nologin. There is a symlink, /sbin/nologin, but that's deprecated and only there for backwards compatibility.

* Don't be too smart, just try packet mode of INT13 first.Yaroslav Tykhiy2004-08-282-5/+9
| | | | | | | | | | | | | | | | | | This way of operation is more robust than the "AI" used before. Add flags to mbr accessible from make.conf as BOOT_MBR_FLAGS. Only one flag is defined now, "allow using packet mode", which is 0x80 in accord with the rest of i386 boot code. The "packet" flag is on by default.

| | | | | | | | | | | | | | | | | | from list_net_interfaces() when network_interfaces=auto. Rationale: Since the auto case is special, the lesser evil had to be chosen among not adding cloned interfaces to _tmplist or removing duplicates from _tmplist after adding cloned interfaces. Since list_net_interfaces() must not use /usr/bin tools, the former "evil" appeared clearer and much more efficient. (See the PR audit trail for discussion.)

* Forced commit to add additional comment.Justin T. Gibbs2004-08-270-0/+0
| | | | | | | | | | | | | | | | | | o Add MOUSE_PS2_TAP into syncmask[0] correctly when we're built with PSM_CONFIG_FORCETAP. The previous code from revision 1.56 attempted to do this but updated the a mask variable that would be clobbered later. o If syncmask[1] hasn't yet been set when ioctl(MOUSE_GETMODE) is called, zero syncmask[0] and syncmask[1] so that sync validation is effectively disabled in userland applications and moused doesn't misbehave. The psm driver performs sync validation so there is no loss in functionality in clearing the sync mask. o If PSM_NEED_SYNCBITS is set, setup syncmask[1], even if it's already correct. This prevents the PSM_NEED_SYNCBITS bit from being left on after a re-initialisation and erroneously causing a subsequent out-of-sync packet to mis-set syncmask[1].

* Improve sync recovery algorithm:Justin T. Gibbs2004-08-272-194/+238
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Remove PSM_SYNCERR_THRESHOLD1. This value specified how many sync errors were required before the mouse is re-initialised. Re-initialisation is now done after (packetsize * 2) sync errors as things aren't likely to improve after that. o Reset lastinputerror when re-initialisation occurs. We don't want to continue to drop data after re-initialisation. o Count the number of failed packets independently of the syncerrors statistic. syncerrors is useful for recovering sync within a single packet. pkterrors allows us to detect when the mouse changes its packet mode due to some external event (e.g. KVM switch). o Reinitialize the mouse if we see more than psmpkterrthresh errors during the validation period. The validation period begins as soon as a sync error is detected and continues until psmerrsecs/msecs time has elapsed. The defaults for these two values force a reset if we see two packet errors in a 2 second period. This allows rapid detection of packet framing errors caused by the mouse changing packet modes. o Export psmpkterrthresh as a sysctl o Export psmloglevel as a sysctl. o Enable more debugging code to be enabled at runtime via psmloglevel. o Simplify verbose conditioned loging by using a VLOG macro. o Add several comments describing the sync recovery algorithm of this driver.

* Move the kernel-specific logic to adjust frompc from MI to MD. ForMarcel Moolenaar2004-08-278-38/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | these two reasons: 1. On ia64 a function pointer does not hold the address of the first instruction of a functions implementation. It holds the address of a function descriptor. Hence the user(), btrap(), eintr() and bintr() prototypes are wrong for getting the actual code address. 2. The logic forces interrupt, trap and exception entry points to be layed-out contiguously. This can not be achieved on ia64 and is generally just bad programming. The MCOUNT_FROMPC_USER macro is used to set the frompc argument to some kernel address which represents any frompc that falls outside the kernel text range. The macro can expand to ~0U to bail out in that case. The MCOUNT_FROMPC_INTR macro is used to set the frompc argument to some kernel address to represent a call to a trap or interrupt handler. This to avoid that the trap or interrupt handler appear to be called from everywhere in the call graph. The macro can expand to ~0U to prevent adjusting frompc. Note that the argument is selfpc, not frompc. This commit defines the macros on all architectures equivalently to the original code in sys/libkern/mcount.c. People can take it from here...
