OS version: Ubuntu 24.04
package version: 18-1build2

My PCs has boot entries 0010, 0020 and 0021.

$ sudo efibootmgr
BootCurrent: 0010
Timeout: 1 seconds
BootOrder: 0020,0010
Boot0010* NORMAL	HD(1,GPT,XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX,0x800,0x80000)/<<snip>>
Boot0020* UPDATE	HD(1,GPT,XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX,0x800,0x80000)/<<snip>>
Boot0021* UEFI: TOSHIBA, Partition 1	PciRoot(0x0)/Pci(0x14,0x0)/USB(16,0)/HD(1,GPT,XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX,0x800,0x80000)0000424f

I tried to active/inactive 10 or 20 entry. But these are not found.

$ sudo efibootmgr -A -b 0010
efibootmgr: Boot entry 10 not found
Could not set active state for Boot0010: No such file or directory
$ sudo efibootmgr -A -b 0020
efibootmgr: Boot entry 20 not found
Could not set active state for Boot0020: No such file or directory
$ sudo efibootmgr -a -b 0010
efibootmgr: Boot entry 10 not found
Could not set active state for Boot0010: No such file or directory
$ sudo efibootmgr -a -b 0020
efibootmgr: Boot entry 20 not found
Could not set active state for Boot0020: No such file or directory

I investigated the cause and found a problem with the get_entry()
function in src/efibootmgr.c.

static var_entry_t *
get_entry(list_t *entries, uint16_t num)
{
 list_t *pos;
 var_entry_t *entry = NULL;

 list_for_each(pos, entries) {
  entry = list_entry(pos, var_entry_t, list);
  if (entry->num != num) {
   entry = NULL;
   continue;
  }
 }

 return entry;
}

This code does not break the loop when an entry is found.
Therefore, NULL is returned unless the matching entry is the last one.
