umip_printk(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ NAME ✨

bestie, welcome to umip_printk(9) from the Kernel API Manual πŸ’– β€” the whole vibe is: print a rate-limited message. that's it. that's the name. slay.


πŸŽ€ SYNOPSIS πŸŽ€

void umip_printk (const struct pt_regs *regs , const char *log_level ,
       const char *fmt , ... );

πŸ’… ARGUMENTS πŸ’…

  • regs β€” register set with the context in which the warning is printed
  • log_level β€” kernel log level to print the message
  • fmt β€” the text string to print
  • ... β€” variable arguments

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so this one prints the text contained in fmt. the print rate is limited to bursts of 5 messages every two minutes β€” yes, 5 whole messages, every two minutes, that's the rate-limit situation, no cap. the purpose of this customized version of printk is to print messages when user space processes use any of the UMIP-protected instructions. so the printed text is prepended with the task name and process ID number of the current task, plus the instruction and stack pointers in regs as seen when entering kernel mode. iconic. πŸ’…

and then the page literally just drops this:

None.

that's it. that's the whole line. None. πŸ’€
