sysctl: Wrap do_proc_douintvec with the public function proc_douintvec_conv

2025-11-27T14:45:38+00:00

Make do_proc_douintvec static and export proc_douintvec_conv wrapper function for external use. This is to keep with the design in sysctl.c. Update fs/pipe.c to use the new public API. Signed-off-by: Joel Granados

sysctl: Create pipe-max-size converter using sysctl UINT macros

2025-11-27T14:45:37+00:00

Create a converter for the pipe-max-size proc_handler using the SYSCTL_UINT_CONV_CUSTOM. Move SYSCTL_CONV_IDENTITY macro to the sysctl header to make it available for pipe size validation. Keep returning -EINVAL when (val == 0) by using a range checking converter and setting the minimal valid value (extern1) to SYSCTL_ONE. Keep round_pipe_size by passing it as the operation for SYSCTL_USER_TO_KERN_INT_CONV. Signed-off-by: Joel Granados

sysctl: Move proc_doulongvec_ms_jiffies_minmax to kernel/time/jiffies.c

2025-11-27T14:45:37+00:00

Move proc_doulongvec_ms_jiffies_minmax to kernel/time/jiffies.c. Create a non static wrapper function proc_doulongvec_minmax_conv that forwards the custom convmul and convdiv argument values to the internal do_proc_doulongvec_minmax. Remove unused linux/times.h include from kernel/sysctl.c. Signed-off-by: Joel Granados

sysctl: Move jiffies converters to kernel/time/jiffies.c

2025-11-27T14:45:37+00:00

Move integer jiffies converters (proc_dointvec{_,_ms_,_userhz_}jiffies and proc_dointvec_ms_jiffies_minmax) to kernel/time/jiffies.c. Error stubs for when CONFIG_PRCO_SYSCTL is not defined are not reproduced because all the jiffies converters go through proc_dointvec_conv which is already stubbed. This is part of the greater effort to move sysctl logic out of kernel/sysctl.c thereby reducing merge conflicts in kernel/sysctl.c. Signed-off-by: Joel Granados

sysctl: Move UINT converter macros to sysctl header

2025-11-27T14:45:37+00:00

Move SYSCTL_USER_TO_KERN_UINT_CONV and SYSCTL_UINT_CONV_CUSTOM macros to include/linux/sysctl.h. No need to embed sysctl_kern_to_user_uint_conv in a macro as it will not need a custom kernel pointer operation. This is a preparation commit to enable jiffies converter creation outside kernel/sysctl.c. Signed-off-by: Joel Granados

sysctl: Move INT converter macros to sysctl header

2025-11-27T14:45:37+00:00

Move direction macros (SYSCTL_{USER_TO_KERN,KERN_TO_USER}) and the integer converter macros (SYSCTL_{USER_TO_KERN,KERN_TO_USER}_INT_CONV, SYSCTL_INT_CONV_CUSTOM) into include/linux/sysctl.h. This is a preparation commit to enable jiffies converter creation outside kernel/sysctl.c. Signed-off-by: Joel Granados

sysctl: Allow custom converters from outside sysctl

2025-11-27T14:45:37+00:00

The new non-static proc_dointvec_conv forwards a custom converter function to do_proc_dointvec from outside the sysctl scope. Rename the do_proc_dointvec call points so any future changes to proc_dointvec_conv are propagated in sysctl.c This is a preparation commit that allows the integer jiffie converter functions to move out of kernel/sysctl.c.

sysctl: Replace void pointer with const pointer to ctl_table

2025-11-27T14:43:20+00:00

* Replace void* data in the converter functions with a const struct ctl_table* table as it was only getting forwarding values from ctl_table->extra{1,2}. * Remove the void* data in the do_proc_* functions as they already had a pointer to the ctl_table. * Remove min/max structures do_proc_do{uint,int}vec_minmax_conv_param; the min/max values get passed directly in ctl_table. * Keep min/max initialization in extra{1,2} in proc_dou8vec_minmax. * The do_proc_douintvec was adjusted outside sysctl.c as it is exported to fs/pipe.c.

sysctl: fix kernel-doc format warning

2025-10-30T12:23:09+00:00

Describe the "type" struct member using '@type' and move it together with the rest of the doc for ctl_table_header to avoid a kernel-doc warning: Warning: include/linux/sysctl.h:178 Incorrect use of kernel-doc format: * enum type - Enumeration to differentiate between ctl target types Fixes: 2f2665c13af4 ("sysctl: replace child with an enumeration") Signed-off-by: Randy Dunlap Signed-off-by: Joel Granados

sysctl: Removed unused variable

2025-07-23T09:56:02+00:00

Remove unaligned_dump_stack from sysctl.h; it is no longer used or defined. Signed-off-by: Joel Granados
