37 hourskernel: exit: Only kill leaf if not exitingIan Moffett
During an exit(), the parent needs to kill all of the child processes that depend on it. However, there might be an occurrence where one or more is already exiting and trying to kill such processes would be problematic and may result in issues like double frees. This commit ensures that the exiting parent only kills child processes that aren't already exiting themselves. Signed-off-by: Ian Moffett <ian@osmora.org>

This commit implements EEPROM reading logic as well as some code to read the ethernet address into a `netif' structure. Signed-off-by: Ian Moffett <ian@osmora.org>

3 dayskernel: e1000: Use raw register VAP offsetsIan Moffett
The E1000 may add padding in-between registers and for the sake of simplicity, we will deal with raw offsets instead of a silly structure. Signed-off-by: Ian Moffett <ian@osmora.org>

4 dayskernel: ctlfs: Do not reclaim ctlfs entriesIan Moffett
There will likely be multiple times the reference count of a ctlfs entry will hit zero. Several programs may open and close a ctlfs node more than once and as these are hardwired kernel objects, they must always stay present. At the most we may set the vp->data field to NULL, indicating that it is currently unused. Signed-off-by: Ian Moffett <ian@osmora.org>

This is no longer needed as the Hyra PMM now does this automatically by default. Signed-off-by: Ian Moffett <ian@osmora.org>
12 dayskernel: Prevent physmem clobbers + zero memoryIan Moffett
To prevent a situation where there is a data race between one thread freeing physical memory and one allocating physical memory. Do not immediately reuse freed physical memory. Instead, keep allocating upwards and once there is no more room, wrap the last_idx back to the bitmap free index. We now also zero allocated physical memory for security reasons.
