| message |
Fix yet another wscons race. In the same subsystem, the following properties must always hold true: 1. A device (wsmouse0 is this scenario) can only be opened in rw mode once. Such device cannot be a child of a wsmux at this point as it operates on its own event queue. 2. A device being a child of a wsmux must use the wsmux event queue assuming the wsmux is open. Otherwise, its event queue must be NULL. There's a race in wsmux_attach_sc() allowing a device to be part of a mux while using its own event queue. This in turn can cause a NULL pointer deference in wsevent_fini() while closing the same device. The solution is to check if the race was lost, i.e. another thread managed to open the device in rw mode while sleeping in wsmux_attach_sc(). ok gnezdo@ visa@ Reported-by: [email protected] |

Introduce constants to access the setjmp(3) jmp_buf fields from i386 libc. The assembler code is more readable than with magic numbers. This brings i386 in line with amd64. No change in object file. OK kettenis@ |

Use 1000baseKX and 2500baseKX media types for fixed link connections an onboard switch. While this technically isn't 100% accurate it gives users an easy way to see what the speed of the connection is when looking at ifconfig(8) output. ok patrick@, benno@, sthen@, phessler@ |

srp_finalize(9): tsleep(9) -> tsleep_nsec(9) srp_finalize(9) spins until the refcount hits zero. Blocking for at least 1ms each iteration instead of blocking for at most 1 tick is sufficient. Discussed with mpi@. ok claudio@ jmatthew@ |

mbg(4): more tsleep(9) -> tsleep_nsec(9) The mbg(4) driver sometimes needs to spin until the MBG_BUSY flag goes away. If the kernel is cold it calls delay(9) for 20us an iteration for up to 50 iterations. If the kernel is not cold it sleeps for up 1 tick per iteration for up to hz/10 iterations. To switch from tsleep(9) to tsleep_nsec(9) claudio@ suggests blocking for at least 1ms per iteration for up to 10 iterations. He reasons that the flag change is expected to take ~70us, so 10 x 1ms (or more) is more than enough. Discussed with mpi@. ok claudio@ |
